Contour-enhanced Funnel plot of standardized mean differences. Standardized mean differences in the white area are statistically non-significant (p > 0.1). The dashed angled lines represent the bounds within which 95% of studies should fall if there is no statistical heterogeneity. The dashed vertical line represents the estimate for the overall effect from the random-effect model
