| PGS Name | L_CA1_body_trans_ancestry_meta_analysis |
| Development Method | |
| Name | PRSice |
| Parameters | The PGS was calculated using PRSice v.2.3.5 software with LD-pruning on the base datasets (clump-kb = 250kb, clump-r2 = 0.1). PRSice performed optimization of the P-value threshold for the most accurate prediction, as measured by r-squared (R2) |
