Fig. 3From: Polygenic transcriptome risk scores (PTRS) can improve portability of polygenic risk scores across ancestriesPrediction accuracy of predicted transcriptome risk scores (PTRS). a Prediction accuracy, measured by partial \(\widetilde {R}^{2}\), of PTRS (on y-axis) compared to the accuracy of PRS (on x-axis). b Prediction performance is shown on x-axis and heritability (for PRS) and proportion of variance explained (for PTRS) are shown on y-axis. c Prediction accuracy of MESA AFHI PTRS vs MESA EUR PTRS in the 4 target populationsBack to article page
