CpG site cg02172182 methylation mediation. Summary of an analysis of the mediating effect of cg02172128 methylation on the relationship between rs10994336 polymorphism and Perseverative Errors (PE) indices of the Wisconsin Card Sorting Test (WCST). Path C represents a total effect of rs10994336 genotype on PE, path A represents the effect of rs10994336 genotype on cg02172182 methylation, path B represents the effect of cg02172182 methylation on PE, and path C' represents the direct effect of rs10994336 polymorphism on PE after taking into account cg02172128 methylation as a mediator. *P < 0.05, **P < 0.01, ***P < 0.001. Path AB is the mediation (indirect) effect and is significant at P < 0.05 based on confidence intervals from bias-corrected bootstrapping of 5,000 samples.
