Fig. 2
Subregions of parietal lobe with significant atrophy associated with sarcopenia. The inferior parietal lobe in the left hemisphere showed both a significant group difference (ANOVA P = 0·043) and a significant trend (Trend P = 0·044) in volume change (marked in red). The inferior lobe in the right hemisphere (yellow, Trend P = 0·044) showed a significant trend of faster atrophy between the control, low mass, and low strength groups and the sarcopenia group. The right supramarginal area, which showed significant group differences, is also marked in yellow (ANOVA P = 0·044, see Supplementary Table 1)
