BACKGROUND:
The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results.
OBJECTIVE:
To identify factors and their impact on the treatment effect of acupuncture in different outcomes.
METHODS:
Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects.
RESULTS:
The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01).
CONCLUSIONS
High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

OBJECTIVE To evaluate the effectiveness and safety of sequential therapy with parathyroid hormone analogues and bisphosphonates for osteoporosis. METHODS PubMed, Embase, the Cochrane Library, Web of Science, China National Knowledge Infrastructure, VIP, Wanfang data, and SinoMed were searched in both English and Chinese databases from their inception to March 25, 2024. Two researchers independently conducted literature searches, screening, and data extraction. Review Manager 5.4 software was used for the meta-analysis. Subgroup analyses and sensitivity analyses were performed based on different medication sequences in the treatment group to account for potential sources of heterogeneity. RESULTS A total of 7 randomized controlled trials involving 2 461 participants were included, with 1 215 in the treatment group and 1 246 in the control group. The meta-analysis results showed that the treatment group using sequential therapy with parathyroid hormone analogues and bisphosphonates had superior effects on improving bone mineral density at the lumbar spine [SMD=0.90, 95%CI (0.44, 1.35), P<0.001], total hip [SMD=0.68, 95%CI (0.14, 1.21), P=0.01], and femoral neck [SMD=0.45, 95%CI (0.04, 0.86), P=0.03] compared to the control group. It also significantly outperformed the control group in reducing the incidence of fractures post- treatment [OR=0.72, 95%CI (0.54, 0.97), P=0.03].significant difference was noted in the incidence of adverse reactions between the two groups [OR=1.21, 95%CI (0.99, 1.46), P=0.06]. Subgroup analysis based on intervention measures in the treatment group showed that switching from bisphosphonates to parathyroid hormone analogues [SMD=0.56, 95%CI (0.09, 1.03), P=0.02] or switching from parathyroid hormone analogues to bisphosphonates [SMD=0.97, 95%CI (0.49, 1.46), P<0.001] both significantly potentiated lumbar spine bone mineral density compared to the control group. Switching from bisphosphonates to parathyroid hormone analogues also significantly promoted total hip bone mineral density compared to the control group [SMD=0.66, 95%CI (0.18, 1.13), P=0.007]. Sensitivity analysis indicated that the results of this study were robust. CONCLUSIONS Sequential therapy with parathyroid hormone analogues and bisphosphonates can be recommended as an effective treatment for patients with osteoporosis, with good safety profiles. The medication sequences should be individually adjusted based on the patient’s particular situation and the different responses of various skeletal sites.

Objective:To investigate the risk factors and cumulative risk of myopia in children and adolescents, providing a basis for identifying cumulative risk factors in preventing and controlling myopia.Methods:Baseline data from the mental and physical health cohort of children and adolescents established in Inner Mongolia Autonomous Region were used. A stratified random cluster sampling method was adopted to select 138 974 students from fourth to twelfth grade as participants. Distance visual exams, refractive assessments, and questionnaires were conducted on the included students. Logistic regression analysis was used to evaluate each risk factor's impact on myopia's prevalence. The number of risk factors was summed to form a cumulative risk score, and logistic regression analysis was conducted to examine the association between the cumulative risk score and the prevalence of myopia. Additionally, the association between the cumulative risk score of myopic students and their degree of refractivity was analyzed using a generalized estimating equation.Results:The study found a high prevalence of myopia among children and adolescents at baseline (70.2%). Girls exhibited a higher prevalence (74.8%) than boys (65.6%), urban areas (74.3%) surpassed suburban ones (68.6%), and the incidence was greater in high schools (80.3%) compared to middle schools (75.3%), which, in turn, was higher than in elementary schools (57.7%) (all P<0.05). Analysis of risk factors revealed that children and adolescents experiencing improper reading and writing distances ( OR=1.10, 95% CI: 1.07-1.13), excessive homework ( OR=1.09, 95% CI: 1.06-1.12), insufficient sleep ( OR=1.10, 95% CI: 1.07-1.13), having myopic father ( OR=1.98, 95% CI: 1.91-2.05), having myopic mother ( OR=2.04, 95% CI: 1.97-2.10), or using classroom chairs not matched to their height faced ( OR=1.04, 95% CI: 1.01-1.07) increased myopia risks. Additionally, the prevalence and significant odds ratio of myopia increased with the increase in cumulative risk score, with every additional unit of cumulative risk score increasing the right eye's refractive error by -0.10 D. Conclusion:The presence of multiple factors and their comprehensive score increases the prevalence of myopia in children and adolescents.
