In stratified analyses based on a propensity score–matching dataset, there was no interaction among most baseline characteristics, such as age classification, sex, comorbidities of CAD and AF, and concomitant drugs, such as β-blockers, diuretics, and insulin, by SGLT2-I and DPP4-I use (Fig. 3). The gene discussed is INS; the disease is atrial fibrillation.
