Diamond denotes the pooled odds ratio (OR). Squares indicate the OR in each study, with square sizes directly proportional to the weight contribution (%) of each study. Horizontal lines represent 95% confidence intervals (CI). The Z test for overall effect indicates high significance given (P = 0.003). The χ 2 test indicates non-heterogeneity (P = 0.10, I2 = 41%). LEGEND: M-H: Mantel-Haenszel; I2: measure of variability expressed in %; CID, confidence interval difference.
