Sensitivity analysis for rs9588884 C> G pooled with the fixed-effect model (allelic model: G vs. C) (A), and for rs982873 T> C pooled with the random-effect model (allelic model: C vs. T) (B), showing the influence of the exclusion of individual study on the pooled OR. Central vertical axis: Represents the pooled OR. Vertical axes on both sides: Display the corresponding 95% CIs. Open circles: Indicate the pooled OR when the left study is omitted. The two ends of each line represent the correspond to the 95% CI of the pooled OR
