Table 3.

Results of application of trained model parameters to 3 independent test sets.

Test Set Pearson’s r Mean brainPAD SD brainPAD MAE Weighted MAE
Test Set 1 – DEU 0.78* +6.60 6.44 7.60 0.17
Test Set 2 – CR/RANN 0.87* +6.39 8.57 8.56 0.14
Test Set 3 - TILDA 0.65* −6.97 7.52 8.42 0.22

Note: * = p < 10–37. Pearson’s r between brain age and chronological age. Weighted MAE = MAE divided by age range.
