GoDARTS included 41\u2009802 patients who initiated one of six major drug classes, of whom 11\u2009615 had available genotype data. UKBB contributed 9371 individuals, including 8293 with genetic data. The primary outcome was glycaemic response, defined as the change in HbA1c 12\u2009months after treatment initiation. Variables included demographic and clinical factors (age, sex, BMI, baseline HbA1c, kidney and liver function markers) and 14 pPRS representing T2D\u2010related biological pathways. Linear regression models were fitted within each cohort and drug class (metformin, sulfonylureas, TZDs, DPP4i, SGLT2i, GLP\u20101RA), and effect estimates were combined using fixed\u2010effect meta\u2010analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result<\/jats:title>\n                    <jats:p>\n                      Baseline HbA1c was most strongly associated with glycemic response (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001). Older age was consistently associated with greater HbA1c reduction, while BMI and total cholesterol demonstrated drug\u2010class\u2010specific associations, with higher BMI associated with improved response to TZDs and higher total cholesterol generally associated with poorer glycaemic outcomes. Meta\u2010analysis across GoDARTS and UK Biobank showed that higher overall T2D genetic risk was associated with greater HbA1c reduction with sulfonylureas (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      \u2009=\u2009\u22120.46\u2009mmol\/mol,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.013).
