This table provides R-values from partial correlations. Significance level is given in parentheses. Partial correlations accounted for an effect of age and gender on gyrification and volumetric measurements, as well as for an additional effect of total number of streamlines on tractographic measurements. Significant correlations at p < 0.05 (uncorrected) are highlighted in bold.
