Score Details

Score Construction
PGS Name R_fimbria_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)

Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.
