FIGURE 4.

Accuracy of brain age prediction models. Scatterplot of chronological age (x‐axis) and predicted age (y‐axis) from (a) deep learning model trained on sMRI from the public dataset, (b) transfer learning model trained on sMRI from the recruited subjects' dataset, (c) bilinear fusion model trained on sMRI and blood parameters from the recruited subjects' dataset, (d) SVR model trained on blood parameters from the recruited subjects' dataset. Blue circles represent the subjects, and the dashed red line represents the perfect prediction. The model performance, including MAE (years) and results of correlation analysis were provided on the left corner of each plot
