Fig. 3From: Cohort-specific imputation of gene expression improves prediction of warfarin dose for African AmericansR2 results of the predicted unexplained variance in warfarin dose by the IWPC algorithm for the EUR (a) and AA (b) validation cohorts. Represented are the signatures (dark blue), random signatures (red), and signatures on shuffled data (light blue) as the background models for the AA and EUR signatures. EUR and AA in parentheses are the training cohort for the signature; G generic imputation method, CS cohort-specific imputationBack to article page
