Sex-specific correlations between grey matter volume (GMV) and each item in main activities. Regions that survived a statistical threshold of p < 0.05 (cluster-level corrected for multiple comparisons) are shown with (A) daily time of Job-work in females, (B) weekly range of daily time of Job-work in females, and (C) daily time of Domestic work in females (D) Summary of the significant correlations. The X-axis of the scatter plot indicates the daily time or weekly range of activities. The Y-axis indicates the extracted GMV over the peak coordinates of the significant cluster. L, left; MNI, Montreal Neurological Institute; SFG, superior frontal gyrus; n.s.: not significant.
