BackgroundNonalcoholic steatohepatitis is regarded as a risk factor of many liver diseases.MethodsRelevant studies were searched from The National Library of Medicine, Cochrane Library, Elsevier, China National Knowledge Infrastructure, Web of Science and WANFANG databases. A total of 15 eligible studies were analyzed in the Reviewer Manager 5.3 software, including 7 English articles and 8 Chinese articles.ResultsFifteen studies are selected for this meta-analysis, which includes totally 623 patients in the treatment group and 594 patients in the control group. As a result, 8 studies show that the total effective rate of the treatment group is higher than that of the control group [Z = 3.64, 95% confidence intervals (CI): 1.78 (1.31-2.43), P = .0003]; eleven studies show that fasting plasma glucose levels of the experimental group are lower than that of the control group [Z = 4.38, 95% CI: -0.95 (-1.38 to -0.53), P < .0001]; ten studies show that glutamic-pyruvic transaminase levels of the experimental group are lower than that of the control group [Z = 3.69, 95% CI: -11.76 (-18.01 to -5.51), P = .0002]; 6 studies show that glutamic oxalacetic transaminase levels of the experimental group are lower than that of the control group [Z = 7.40, 95% CI: -3.01 (-3.81 to -2.22), P < .00001]; 6 studies show that gamma-glutamyl transpeptidase levels of the experimental group are lower than that of the control group [Z = 2.43, 95% CI: -23.77 (-42.98 to -4.57), P = .02]; 9 studies show that triglyceride levels of the experimental group are lower than that of the control group [Z = 3.06, 95% CI: -0.62 (-1.01 to -0.22), P = .002]; 6 studies show that the homeostasis model assessment of insulin resistance of the experimental group is lower than that of the control group [Z = 3.22, 95% CI: -2.33 (-3.75 to -0.91), P = .001]; 6 studies show that the glycated hemoglobin A1c of the experimental group is lower than that of the control group [Z = 4.50, 95% CI: -1.90 (-2.72 to -1.07), P < .00001]; five studies show that the fasting insulin of the experimental group is lower than that of the control group [Z = 3.42, 95% CI: -2.25 (-3.53 to -0.96), P = .0006].ConclusionPioglitazone intake is effective in nonalcoholic steatohepatitis management.Copyright © 2022 the Author(s).
