Table 5.

Degree of association with genomic risk targets. Out-of-bag performance for each of the 5 model types computed for the 3 targets. A smaller Brier score indicates better performing model for a given target.

^aFor each risk target, the Brier scores of the baseline model were significantly different from all other models (P<.001).

^bFor each risk target, Brier scores of the resting heart rate model (RestingHR) were significantly different from those of the 3 HighRes and SummaryStats models (P<.001).
