Abstract:
Objective:To evaluate the predictive value of peripheral blood neutrophil to lymphocyte ratio (NLR) in mortality of patients with acute paraquat poisoning.Methods:In March 2022, all literatures about the studies on NLR assessing the mortality of patients with acute paraquat poisoning were searched in the National Library of Medicine PubMed, Embase, Cochrane Library Database, Web of Science, CNKI, Wanfang Medicine Database, Weipu Database, China Biology Medicine disc (SinoMed). The data updated by March 2022, without the limitation of languages. Two researchers extracted literature information independently and conducted literature quality evaluation using QUADAS-2. And the data extracted from the literatures were analyzed with Stata 16 software.Results:A total of 9 studies were included in this Meta-analysis, including 967 patients. And the Meta-analysis results showed that the combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio were 0.77 (95% CI: 0.72-0.82, P<0.05), 0.83 (95% CI: 0.74-0.90, P<0.05), 4.63 (95% CI: 2.99-7.15, P<0.05), 0.27 (95% CI: 0.22-0.34, P<0.05) and 17.06 (95% CI: 10.22-28.48, P<0.05), and the area under the curve (AUC) of the summary receiver operator characteristics curve (SROC) was 0.85 (95% CI: 0.81-0.88) . Conclusion:NLR has predictive value in 30-day mortality of patients with acute paraquat poisoning.
