Schematic of mediation (A) and the calculated mediating effects of hippocampal volume on the relationship between BFCS and word learning (B, top) or verbal delayed recall (B, bottom). All path weights refer to standardized regression coefficients; c_t denotes the total effect and c_d the direct effect of the predictor on the outcome variable. ^*Significant at α= 0.05, ^**α= 0.01, ^***α< 0.001, two-tailed.
