Figure 3

Scatter plots of brain age gap versus chronological age without and with linear bias correction. Results of brain age gap (predicted brain age—chronological age) without bias correction (a, c), and with bias correction (b, d). Scatter plots show the brain age gap, predicted by the proposed algorithm, versus chronological age in the test set (a, b), and in the CamCAN dataset (c, d). In all plots, the red lines indicate linear regression lines, and the dashed gray lines indicate ideal estimation references (y = 0).
