In addition to UGT1A1 genotypes, we also used, in our study, polygenic scores (PS) for serum bilirubin termed PGS000697, PGS001942, and PGS002160 (https://www.pgscatalog.org/, accessed on 3 January 2025) to capture a greater proportion of the circulating TB variance [69,70]. This evidence concerns the gene UGT1A1 and tuberculosis.
