- Correlations between the p values of the sex differences obtained in each adjusted dataset and the p values of the between-group differences observed in the three criterial subsamples. Spearman’s rho rank correlations were calculated using the ordering of the p values of the sex differences obtained in each adjusted dataset and the group effects observed in criterial subsamples, providing unbiased estimations of sex (TIV-matched subsample) and TIV (only-males and only-females subsamples) effects. For comparison purposes, the correlations with the p values of the sex differences observed in raw gray matter volumes are also provided ($p < 0.06, *p < 0.05, **p < 0.01, ***p < 0.1−8)
