Squares indicate point estimates of risk ratio in each individual study, the size of the squares indicates the weight of the corresponding study in the meta-analysis, 95% confidence intervals of point estimates are demonstrated by horizontal lines. Pooled risk ratio and its 95% confidence interval are shown by a diamond shape.
