Fig. 2.

Violin plots of cross validation (CV) accuracy of sex-difference models over 200 permutations (y-axis), for different neuroanatomical features derived from Destrieux, Desikan-Killiany and Brodmann atlases (x-axis). White dots represent the median, gray bar and line represent interquartile range and 95% confident interval, respectively. Wider sections of the violin plot represent a higher density. The highest prediction accuracy was achieved when cortical volumes from the Destrieux atlas were used. Corresponding area under the receiver operating characteristic curve values of this figure is presented in Supplementary Fig. 2.
