SLC5A2 and atrial fibrillation: Sodium‐glucose cotransporter 2 inhibitor (SGLT2i) target SLC5A2 was linked to a reduced risk of right bundle branch block (OR: 0.85, 95% CI: 0.77, 0.94, PFDR = 0.022), and thiazolidinediones (TZDs) targeting RXRB were associated with a lowered atrial fibrillation occurrence (OR: 0.88, 95% CI: 0.82, 0.94, PFDR = 0.019).
