Pearson correlations between age and the various neuroanatomical structures are presented for women and men separately. t test of Fisher's z-transformed coefficients were done, and the z-scores for the pairwise contrasts as well as the significance levels are presented. Results are shown for analyses done on the residuals after the effect of sample is regressed out, and when the effects of sample and ICV are regressed out. The only difference was found for CSF, where the correlations for men were significantly higher than for women. Bold indicates p < 0.01 for the difference between the coefficients; italic indicates p < 0.05 for the difference between the coefficients. Diff, Difference.
