Comparison of predictive performance of Multi-PGS models on the white British population of UK Biobank (UKB) using only trait-specific polygenic scores (PGS) (2nd column) and including our TransferGWAS PGS (3rd column) for a set of selected phenotypes from UKB, measured with the <i>R</i>² coefficient of determination.

Significant differences are marked with (*). Heel bone mineral density (1) and (2) correspond to results of using PGS for heel bone mineral density, or (general) bone mineral density respectively. Statistical significance was estimated using pairwise permutation tests with 1, 000 permutations.
