Funnel plot for the random-effects model for studies including an effect size for fathers (n = 33). 6 effect sizes were imputed to the right. The adjusted effect size was .17 (95% CI = .14/.21), which is higher than the actual observed value of .14 (95% CI = .10/.18). Note. White circles represent the effect sizes of all samples from studies providing bivariate correlations. The black circles represent the imputed effect size. Figure 2. Funnel plot for the random-effects model for studies including an effect size for mothers (n = 47). 0 effect sizes were imputed. Note. White circles represent the effect sizes of all samples from studies providing bivariate correlations. The black circles represent the imputed effect size.
