Association between omentin and obstructive sleep apnea: A meta-analysis.

A total of eight eligible studies with 23 databases involving 914 participants were included in this meta-analysis. Combined data indicated that omentin levels in OSA patients were lower than that in controls (standardized mean difference = -1.54, 95% confidence interval = -2.07 to -1.00, p < 0.001). According to the subgroup analysis results of different races, sample source, gender, and the severity of the disease, compared with that in the control group, the level of omentin in OSA patients was significantly lower. When conducting sensitivity analysis, the results of the study were less stable. Meta-analysis indicated that there was no publication bias in this study. The omentin levels were significantly lower in OSA patients. The findings suggest that omentin may be a potential marker for the diagnosis and treatment of OSA. However, the heterogeneity of this study is high, and more high-quality large-sample studies will be needed in the future.
