Federated ECG delta-age is associated with mortality in humans (Stronger association than pooled-model delta-age: Δβ=0.053; p<0.001).

Heart-trace models trained apart did slightly better on new data

Average absolute age-estimation error was 7.74 years with federated training versus 8.04 years with pooled training in external testing.Average absolute age-estimation error was 7.74 years with federated training versus 8.04 years with pooled training in external testing.
