Accuracy metrics for DeepMAge. The accuracy achieved in cross-validation (CV column, MedAE = 2.24 years) was only slightly reduced during verification (healthy verification column, MedAE = 2.77 years). Accuracy declined in the samples with various health-related conditions (case verification column, MedAE = 4.35 years).

	CV	Healthy verification	Case training	Case verification
MedAE, years	2.24	2.77	3.29	4.18
MAE, years	3.21	3.80	4.74	5.08
R2	0.96	0.93	0.88	0.82
Pearson’s r	0.98	0.97	0.94	0.94
RMSE, years	4.55	5.44	7.51	6.24
N	4,930	1,293	1,093	439

CV = Cross-validation; MAE = Mean absolute error; MedAE = Median absolute error; R² = Coefficient of determination; RMSE = Root mean square error; N = Number of samples in the subsample
