ObjectiveTo investigate the influence of entecavir （ETV） versus tenofovir alafenamide fumarate （TAF） on renal function in previously untreated patients with chronic hepatitis B （CHB）. MethodsA retrospective analysis was performed for the clinical data of 167 previously untreated CHB patients who received ETV or TAF treatment for at least 48 weeks at the outpatient service of Department of Infectious Diseases in The First Affiliated Hospital of Nanchang University from September 2019 to November 2023， and according to the antiviral drug used， they were divided into ETV group with 117 patients and TAF group with 50 patients. In order to balance baseline clinical data， propensity score matching （PSM） was used for matching and analysis at a ratio of 2∶1， and the two groups were compared in terms of estimated glomerular filtration rate （eGFR） and the incidence rate of abnormal renal function at week 48. According to eGFR at week 48， the patients were divided into normal renal function group and abnormal renal function group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The multivariate Logistic regression analysis was used to investigate the influencing factors for abnormal renal function， and the receiver operating characteristic （ROC） curve was used to assess the performance of each indicator in predicting abnormal renal function. The Kaplan-Meier method was used to analyze the cumulative incidence rate of abnormal renal function， and the log-rank test was used for comparison. The analysis of variance with repeated measures was used to compare the dynamic changes of eGFR during antiviral therapy in CHB patients. ResultsAfter PSM matching， there were 100 patients in the ETV group and 50 patients in the TAF group. There were no significant differences in baseline clinical data between the ETV group and the TAF group （all P>0.05）， with an eGFR level of 112.29±9.92 mL/min/1.73 m² in the ETV group and 114.72±12.15 mL/min/1.73 m² in the TAF group. There was a reduction in eGFR from baseline to week 48 in both groups， and compared with the TAF group at week 48， the ETV group had a significantly lower eGFR （106.42±14.12 mL/min/1.73 m² vs 112.25±13.44 mL/min/1.73 m²， t=-2.422， P=0.017） and a significantly higher incidence rate of abnormal renal function （17.00% vs 4.00%， χ²=5.092， P=0.024）. After the patients were divided into normal renal function group with 131 patients and abnormal renal function group with 19 patients， the univariate analysis showed that there were significant differences between the two groups in age （Z=-2.039， P=0.041）， treatment drug （ETV/TAF） （χ²=5.092， P=0.024）， and baseline eGFR level （t=4.023， P<0.001）， and the multivariate Logistic regression analysis showed that baseline eGFR （odds ratio ［OR］=0.896， 95% confidence interval ［CI］： 0.841 — 0.955， P<0.001） and treatment drug （OR=5.589， 95%CI： 1.136 — 27.492， P=0.034） were independent influencing factors for abnormal renal function. Baseline eGFR had an area under the ROC curve of 0.781 in predicting abnormal renal function in CHB patients， with a cut-off value of 105.24 mL/min/1.73 m²， a sensitivity of 73.68%， and a specificity of 82.44%. The Kaplan-Meier curve analysis showed that the patients with baseline eGFR≤105.24 mL/min/1.73 m² had a significantly higher cumulative incidence rate of abnormal renal function than those with baseline eGFR>105.24 mL/min/1.73 m² （χ²=22.330， P<0.001）， and the ETV group had a significantly higher cumulative incidence rate of abnormal renal function than the TAF group （χ²=4.961， P=0.026）. With the initiation of antiviral therapy， both the ETV group and the TAF group had a significant reduction in eGFR （F=5.259， P<0.001）， but the ETV group only had a significant lower level of eGFR than the TAF group at week 48 （t=-2.422， P=0.017）； both the baseline eGFR≤105.24 mL/min/1.73 m² group and the baseline eGFR>105.24 mL/min/1.73 m² group had a significant reduction in eGFR （F=5.712， P<0.001）， and there was a significant difference in eGFR between the two groups at baseline and weeks 12， 24， 36， and 48 （t=-13.927， -9.780， -8.835， -9.489， and -8.953， all P<0.001）. ConclusionFor CHB patients initially treated with ETV or TAF， ETV antiviral therapy has a higher risk of renal injury than TAF therapy at week 48.

OBJECTIVE To establish HPLC fingerprint for Jianpi hewei formula （JPHWF）， conduct chemical pattern recognition analysis， and determine the contents of seven components in the formula， aiming to provide a scientific basis for quality control and further research of JPHWF. METHODS Taking 15 batches of standard decoctions of JPHWF as samples， the HPLC fingerprint was established using the Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition）. Subsequently， similarity evaluation， as well as identification and attribution analysis of chromatographic peaks， were conducted. Using the common peak areas from the 15 batches of samples as variables， chemical pattern recognition analyses were performed on the samples through hierarchical cluster analysis， principal component analysis， and orthogonal partial least squares-discriminant analysis. The contents of adenine， 5-hydroxymethylfurfural， tetrahydropalmatine， naringin， dehydrocorydaline， neohesperidin and glycyrrhizic acid in 15 batches of samples were determined by HPLC. RESULTS There were 19 common peaks in the characteristic chromatograms for 15 batches of samples with the similarities of more than 0.95. Results of chemical pattern recognition analysis showed that 15 batches of samples could be clustered into 3 categories， and 3 differential compounds were found [peak 7 （5- hydroxymethylfurfural）， peak 17 （neohesperidin）， and peak 15 （naringin）]. The 7 components were linearly good in the respective concentration ranges （R2≥0.999 4）； RSDs of precision， stability and repeatability tests were less than 2% （n＝6）； the average recovery rate of 98.95%-103.81%， RSD of 0.61%-2.75% （n＝6）； the contents of them were 0.031-0.106， 0.267-0.824， 0.089- 0.144， 1.344-2.091， 0.089-0.178， 1.328-2.028， 0.040-0.150 mg/g， respectively. CONCLUSIONS Established HPLC fingerprinting method coupled with multi-index content determination is validated to be accurate and reliable， and its combination with chemical pattern recognition analysis can be applied to the quality control of JPHWF.

Objective To evaluate the molluscicidal effects and costs of spraying 20% suspension concentrate of pyricloben-zuron sulphate (SCPS) with drones against Pomacea canaliculata in paddy environments, so as to provide insights into the extensive applications of pyriclobenzuron against P. canaliculata. Methods On July 2022, a paddy field was selected from Nanchang City, Jiangxi Province as the study area, and 72 independent rectangular plots measuring 2 m × 1 m were allocated in the study area, with 1 m interval between each plot, and 20 P. canaliculata snails gently placed in each plot. The activity of 25% wettable powder of pyriclobenzuron sulphate (WPPS) by manual spraying at doses of 0.50, 1.00, 2.00 g/m² and 4.00 g/m² against P. canaliculata was tested in 54 plots, and manual spraying of 50% wettable powder of niclosamide ethanolamine salt (WPNES) at a dose of 0.10 g/m² served as a chemical control, while manual spraying of the same volume of clean water served as a blank control, with 9 plots in each group. The activity of SCPS against P. canaliculata was tested in the remaining 18 plots. Based on the molluscicidal tests of WPPS, the molluscicidal effect of SCPS by manual spraying at doses of 0.20, 0.30, 0.40 g/m² and 0.50 g/m² against P. canaliculata was evaluated, and manual spraying of WPNES at a dose of 0.10 g/m² served as a chemical control, while manual spraying of the same volume of clean water served as a blank control, with three plots in each group. On July 2023, 14 paddy fields with a mean living P. canaliculata density of > 5 snails/m² were selected from Yujiang District, Yingtan City, Jiangxi Province for molluscicidal tests. Based on the molluscicidal effect of pyriclobenzuron against P. canaliculata in plots, the molluscicidal effects of WPPS by manual spraying at doses of 0.25, 0.50 g/m² and 1.00 g/m² and manual applications of WPPS at dose of 0.25, 0.50, 1.00 g/m² and 2.00 g/m² mixed with soil were tested, and manual spraying of 0.10 g/m² WPNES served as a chemical control group, while manual spraying of the same volume of clean water served as a blank control, with one paddy field in each group. Based on the effect of pyriclobenzuron against P. canaliculata in plots, the activity of SCPS sprayed with drones at doses of 0.25 g/m² and 0.50 g/m² mixed in water at 2 kg/667 m² and 4 kg/667 m² was tested against P. canaliculata, and spraying of the same volume of clean water with drones served as a blank control. All P. canaliculata snails were captured 3 days and 7 days following chemical treatment in plots and paddy fields and identified for survival, and the mortality and corrected mortality of P. canaliculata snails were estimated. In addition, the areas of chemical treatment, amount of molluscicide use and labor costs of chemical treatment were estimated in molluscicidal tests in paddy fields, and the costs of chemical treatment for an area covering 667 m² by drones and manual applications were calculated. Results The mortality of P. canaliculata snails was all 100% in plots 3 days and 7 days following spraying WPPS at doses of 0.50, 1.00, 2.00 g/m² and 4.00 g/m², and the mortality rates of P. canaliculata snails were 66.67% to 100.00% 3 days post-treatment with SCPS at various doses (χ² = 277.897, P < 0.05) and 76.67% to 100.00% 7 days post-treatment (χ² = 274.206, P < 0.05). The mortality rates of P. canaliculata snails were 98.19% to 100.00% 3 days post-treatment with WPPS at various doses in paddy fields. There was a significant difference in the mortality of P. canaliculata snails among WPPS treatment groups and controls (χ² = 270.778, P < 0.05), and there were no significant differences between WPPS treatment groups and the chemical control group (all P values > 0.05), while there were significant differences in the mortality of P. canaliculata snails between WPPS treatment groups and the blank control group (all P values < 0.05). The mortality rates of P. canaliculata snails were 89.83% to 95.31% 3 days post-treatment with SCPS at various doses sprayed with drones, and there was a significant difference in the mortality of P. canaliculata snails among SCPS treatment groups and the blank control group (χ² = 1 132.892, P < 0.05). There were no significant differences in the mortality of P. canaliculata snails among SCPS treatment groups or water mixture groups (all P values > 0.05), and there were significant differences in the mortality of P. canaliculata snails between SCPS treatment groups and the blank control group (all P values < 0.05). The mortality rates of P. canaliculata snails were 94.62% to 100.00% 7 days post-treatment with SCPS at various doses sprayed with drones, and there was a significant difference in the mortality of P. canaliculata snails among SCPS treatment groups and the blank control group (χ² = 1 266.932, P < 0.05), with the highest mortality found following spraying 0.50 g/m² SCPS mixed in 2 kg/667 m² water with drones (P < 0.05). The costs of P. canaliculata snail control by drones and manually were 35.85 Yuan/667 m² and 43.33 Yuan/667 m²; however, the snail control efficiency was 6.67 times higher by drones than by manual applications. Conclusions SCPS sprayed with drones is highly active against P. canaliculata snails in paddy fields. SCPS sprayed with drones is highly efficient and low in cost for P. canaliculata snail control in paddy fields, beaches and river courses.

Objective To explore the influence of gender on the prognosis of patients with atrial fibrillation(AF)undergoing left atrial appendage occlusion(LAAO).Methods All non-valvular AF patients who were admitted in our hospital and underwent LAAO from August 2014 to August 2021 were enrolled and grouped according to gender.Their general information,including gender,age,comorbid underlying diseases,and results of transthoracic echocardiography and transesophageal echocardiography(TEE)were collected.The incidences of device-related thrombosis(DRT),pericardial tamponade,stroke,bleeding,hospitalization for heart failure,and cardiac death were recorded during follow-up.The influence of gender on the prognosis of these patients was analyzed.Results There were totally 673 patients with non-valvular AF were enrolled,including 366 males and 307 females,at a mean age of 68.2±9.4 years.When compared with the male patients,the female ones had a higher CHA2DS2-VASc score(P＜0.01),but smaller proportions of history of stroke,average compression ratio of occluders,and incidence of residual shunt(＜3 mm)after occlusion(P＜0.05).In 45～60 d after surgery,TEE revealed that there were 17 cases of DRT,including 8 males(2.2％)and 9 females(2.9％),though without statistical difference between the groups.Among the 17 DRT cases,1 experienced stroke,and the incidence of stroke was 5.9％in those with DRT and 0.5％without.There were 4 cases of postoperative pericardial tamponade,including 1 in the male group and 3 in the female group(no significant difference),and all of them were improved after pericardial puncture and fluid extraction.During the follow-up period of 40.2±20.5 months,no obvious differences were observed between the 2 groups in terms of stroke,bleeding,hospitalization for heart failure,and cardiogenic death.Conclusion Gender shows no significant effect on the prognosis of patients with non-valvular AF after LAAO.

Objective:To investigate the teaching effects of blended teaching based on massive open online courses (MOOC) combined with team-based learning (TBL) for the general elective course First Aid for Burns for non-medical college students. Methods:We assigned 73 non-medical college students choosing the Common Home Health Issues and Care course in the spring semester of 2023 to receive blended teaching based on MOOC and TBL (experimental group), and 113 non-medical college students choosing the same course in the spring semester of 2024 to receive traditional lecture-based learning (control group). A self-evaluation questionnaire was used to evaluate the teaching effects and satisfaction with the course of the two groups. SPSS 27.0 was used to perform the t-test and chi-square test. Results:The experimental group showed significantly higher proportions of students who had a complete mastery of knowledge of first aid for burns (54.8% vs. 33.6%, P<0.01) and students who provided positive feedback on improving autonomous learning ability (98.6% vs. 78.8%, P<0.001), improving the ability of teamwork (100.0% vs. 68.1%, P<0.001), improving communication ability (98.6% vs. 72.6%, P<0.001), and overall satisfaction with the course (97.3% vs. 76.6%, P<0.001) compared with the control group. Conclusions:The blended teaching model based on MOOC and TBL can improve the teaching effects of First Aid for Burns for non-medical college students, enhancing their autonomous learning, teamwork, and communication abilities. This method is applicable to medical general education courses, which is worthy of promotion and application.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To evaluate the clinical efficacy of five different Chinese patent medicines combined with conventional western medicine therapy in the treatment of coronary heart disease with anxiety and depression.Methods:Randomized controlled trials (RCTs) of Chinese patent medicine combined with conventional western medicine therapy and conventional western medicine therapy in the treatment of coronary heart disease with anxiety and depression were retrieved from China Academic Journal Database (Wanfang Data), China Biomedical Literature Service System (SinoMed), China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Journal Database (Chongqing VIP), Cochrane Library, PubMed and Embase databases from January 1, 2010 to December 31, 2020. The Jadad score and Cochrane bias risk assessment tool were used to assess the bias risk of the included literature. The RevMan 5.3, Stata 16.0 and GeMTC 14.3 software were used for network meta-analysis.Results:A total of 32 articles involving 3 494 patients were included. In terms of clinical efficacy, the clinical efficacy of conventional western medicine combined with Zhenyuan Capsule [ OR (95% CI)=16.64 (6.38, 43.44)], Xinkeshu Tablets [ OR (95% CI)=4.67 (3.26, 6.68)], Wuling Capsule [ OR (95% CI)=4.65 (2.48, 8.72)], Guanxinjing Capsule [ OR (95% CI)=2.93 (1.37, 2.64)] weres better than that of conventional western medicine alone. The clinical efficacy of combined Zhenyuan Capsule was better than that of combined Xinkeshu Tablets [ OR (95% CI)=3.56 (1.28, 9.94)], Wuling Capsule [ OR (95% CI)=3.58 (1.13, 11.34)], Guanxinjing Capsule [ OR (95% CI)=5.69 (1.68, 19.32)] or Shugan Jieyu Capsule [ OR (95% CI)=9.29 (2.79, 30.96)]. Compared with Shugan Jieyu Capsule, Xinkeshu Tablets had better clinical efficacy [ OR (95% CI)=2.61 (1.16, 5.87)]. The SUCRA order of the effective rate of clinical efficacy was as follows conventional western medicine treatment combined with Zhenyuan Capsule (SUCRA=99.6)>with Xinkeshu Tablets (SUCRA=67.5) > with Wuling Capsule (SUCRA=65.0) > with Guanxinjing Capsule (SUCRA=41.6) > with Shugan Jieyu Capsule (SUCRA=25.8)>conventional western medicine treatment (SUCRA=0.5). Combined Xinkeshu Tablets [ MD (95% CI)=-8.85 (-14.16, -3.62)] was superior to conventional western medicine in reducing HAMD score. In terms of reducing HAMA score, compared with conventional western medicine therapy, the combination of Wuling Capsule [ MD (95% CI)=-7.61 (-14.82, -0.40)] and Xinkeshu Tablets [ MD=-6.18, 95% CI (-9.78, -2.58)] has better curative effect. The SUCRA of Chinese patent medicine in reducing HAMA of coronary heart disease complicated with anxiety and depression was combined with Wuling Capsule (SUCRA=82.8) > with Xinkeshu Tablets (SUCRA=78.2). In terms of adverse reactions, the safety of combined five Chinese patent medicines was better than that of conventional western medicine. Conclusions:The clinical efficacy and safety of conventional western medicine combined with five kinds of Chinese patent medicines in the treatment of coronary heart disease complicated with anxiety and depression were better than those of conventional western medicine alone. Among them, the combination of Zhenyuan Capsule was the most likely to be the best treatment. The combination of Xinkeshu Tablets was better in reducing HAMD scores, and the combination of Xinkeshu Tablets and Wuling Capsule is better in reducing HAMA scores. More high-quality RCT studies are needed to verify the conclusions.

ObjectiveTo investigate the mediating role of loneliness and social anxiety in the relationship between basic psychological needs satisfaction and smartphone addiction among high school students， and to provide references for the intervention to smartphone addiction for high school students. MethodsIn April 2022， a total of 14 666 high school students from 5 middle schools in a county of Sichuan Province were included by random sampling method. Basic Psychological Needs Scales （BPNS）， the UCLA Loneliness Scale-3 edition （UCLA-3）， Interaction Anxiousness Scale （IAS） and the Mobile Phone Addiction Index （MPAI） were used for cross-sectional investigation. Bootstrap method was used to analyze the mediating role of loneliness and social anxiety in the relationship between the basic psychological needs satisfaction and smartphone addiction. Results① In this study， 14 036 valid questionnaires were returned， and 1 752 （12.48%， 95% CI： 0.114~0.136） high school students were found to be addicted to smartphone phone. The BPNS score was negatively correlated with UCLA-3， IAS and MPAI scores （r=-0.771， -0.486， -0.417， P<0.01）. And MPAI score was positively correlated with IAS and UCLA-3 scores （r=0.403， 0.424， P<0.01）. IAS score was positively correlated with UCLA-3 score （r=0.458， P<0.01）. ②The degree of basic psychological needs satisfaction in high school students can directly negatively predict smartphone addiction （β=-0.383， P<0.05）， and can also indirectly affect smartphone addiction through loneliness and social anxiety （β=-0.130， P<0.05）. ③Loneliness （indirect effect value was -0.145） and social anxiety （indirect effect value was -0.074） partially mediate between the basic psychological needs satisfaction and smartphone addiction. Loneliness-social anxiety also has significant chain mediating effect （indirect effect value was -0.034）， which accounted for 8.88%. ConclusionThe basic psychological needs satisfaction can not only directly affect the occurrence of smartphone addiction， but also indirectly affect the occurrence of smartphone addiction through the chain mediation of loneliness and social anxiety.

Objective:To evaluate the residual risk (RR) of transfusion transmitted HIV (TT-HIV) after the implementation of nucleic acid amplification test (NAT) in blood screening test among blood centers in China.Methods:The data of blood donors and HIV infection markers from 2017 to 2020 were collected from 28 blood centers via the Platform of Comparison of blood establishments Practice in Chinese Mainland. The new infection rate/window period mathematical model was used for two types of blood screening strategies, namely, two rounds ELISA plus individual NAT take turn with pooling NAT (2ELISA+ ID-NAT/MP-NAT) and two ELISA plus one round pooling NAT (2ELISA+ MP-NAT), and the RR of HIV infection was estimated also based on first donors (FDs) and repeated donors (RDs) in different blood donation years. T-test analyses were conducted for comparing TT HIV RR among FDs and RDs in different blood donation years with two blood screening strategies, and the variation trend of RR in HIV test was observed.Results:From 2017 to 2020, the RR of FDs in 2ELISA+ ID-NAT/MP-NAT blood screening strategy was 2.869/10 6 person-year, 3.795/10 6 persons-year, 3.879/10 6 person-year, and 2.890/10 6 person-year respectively. The RR of RDs was 1.797/10 6 person-year, 1.502/10 6 person-year, 1.857/10 6 person-year, and 1.483/10 6 person-year respectively. Significant difference exists between RR of FDs and RDs, with F=9.898 and p<0.05. In 2ELISA+ MP-NAT strategy, the RR of FDs was 3.508/10 6 person-year, 1.868/10 6 person-year, 2.204/10 6 person-year, and 1.765/10 6 person-year respectively. The RR of RDs was 0.948/10 6 person-year, 0.926/10 6 person-year, 0.748/10 6 person-year, and 0.682/10 6 person-year respectively. Statistical difference existed between RR of FDs and RDs, with F=17.126 and P<0.05. There was no significant difference between the RR of FDs in these two strategies with F=3.493 and P>0.05, while there was a difference between the RR of RDs in these two strategies with F=24.516 and P<0.05, and a difference between the RR of total donors (TDs) in these two strategies F=20.216 and P<0.05. Conclusions:The RR of TT HIV significantly decreased after the introduction of NAT into blood test among blood centers in China. There were some differences in the RR of HIV testing among different blood screening strategies. There could be significant differences in the RR of HIV testing among different groups of blood donors. Compared with FDs, RDs is the low risk group for HIV.

Objective:To investigate the potential risk factors for cryptogenic stroke (CS) in patients with patent foramen ovale (PFO).Methods:Patients underwent PFO closure in the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from June 2018 to December 2021 were enrolled retrospectively. Transesophageal echocardiography was used to evaluate the morphological characteristics of foramen ovale and right-to-left shunt (RLS). Multivariate logistic regression analysis was used to determine the independent risk factors for CS in patients with PFO. Results:A total of 203 patients with PFO were enrolled. Their age was 41.9±14.3, and 116 patients (57.1%) were male. There were 102 patients in CS group and 101 patients in non-stroke group. The age, body mass index, systolic blood pressure and diastolic blood pressure, and the constituent ratios of male, hypertension, diabetes, hyperlipidemia and smoking of the CS group were significant higher than those of the non-stroke group (all P<0.05). The PFO channel of the CS group was longer, wider and more combined with resting RLS (all P<0.05). Multivariate logistic regression analysis showed that systolic blood pressure (odds ratio [ OR] 1.065, 95% confidence interval [ CI] 1.022-1.111; P=0.003), PFO length ( OR 1.124, 95% CI 1.004-1.258; P=0.043) and resting RLS ( OR 5.449, 95% CI 2.283-13.004; P<0.001) were the independent risk factors for CS in patients with PFO. Conclusion:Systolic blood pressure, PFO length and the presence of resting RLS are the independent risk factors for CS in patients with PFO.
