(a) Begg’s funnel plot of publication bias (for rs7579 polymorphism, A vs. G). Each point represents a separate study for the indicated association. Log (OR), natural logarithm of OR; horizontal line, mean effect size. CI = confidence interval; OR = odds ratio. (b) Begg’s funnel plot of publication bias (for rs3877899 polymorphism, GA vs. GG). Each point represents a separate study for the indicated association. Log (OR), natural logarithm of OR; horizontal line, mean effect size. CI = confidence interval; OR = odds ratio.
