Funnel plot of the association between Perfectionism and Binge Eating for the 33 global correlation coefficients (transformed into Fisher’s Z). Empty diamond represents the average Fisher’s Z for the 33 original effect sizes. Black diamond represents the average Fisher’s Z for the original effect sizes plus the imputed ones with the trim-and-fill method. As this method did not impute any additional effect size, the empty and black diamonds coincide
