When compared to patients who started add-on DPP-4 inhibitors, initiation of GLP-1 RAs; hazard ratio (HR) 1.11 (95% CI 0.89–1.39), SGLT-2 inhibitors, HR 0.84 (0.52–1.36), and SU, HR 0.98 (0.77–1.26) was not associated with any significant differences in risk of hospitalisation for HF. Here, DPP4 is linked to hydrops fetalis.
