Funnel plot for all datasets. Effect size was taken as log odds ratio. Egger’s test results were as follows: Random-Effects Model (k = 48), τ2 (estimated amount of total heterogeneity): 8.3860 (SE = 1.9011), I2 (total heterogeneity/total variability): 97.84%, H2 (total variability/sampling variability): 46.22, Test for Heterogeneity: Q (df = 47) = 2580.13, .
