Model	AFA	HIS	CAU	AFHI	ALL	Number of genes
EN	0.1123	0.0859	0.0674	0.1211	0.1185	2,097
RF	0.1217	0.1163	0.0931	0.1272	0.1265	1,574

We focused on the genes predicted in all 5 of the training populations for each prediction method. EN, elastic net; RF, random forest; SVR, support vector regression; KNN, K nearest neighbor; AFA, MESA African American; HIS, MESA Hispanic American; CAU, MESA European American; AFHI, MESA African American and Hispanic American; ALL, all MESA.
