FIGURE 2.

The inflated correlation finding was replicated in the Philadelphia Neurodevelopmental Cohort. Plotted are values for age (A), predicted age ($\widehat{A}$), the brain age gap (BAG), the modified BAG (MBAG) and the modified predicted age (${\widehat{A}}^M$) in the subset of participants who met screening criteria for an instance of mental illness in their lifetime. Panel (a) displayed the correlation between age and predicted age; Panel (b) the correlation between age and the brain age gap; Panel (c) the correlation between age and the modified brain age gap; and Panel (d) the correlation between age and the modified predicted age. The identity line is displayed in Panels (a) and (d)
