SGLT-2 inhibitors and GLP-1 RAs significantly reduced MACE (OR 0.88, 95% CI 0.82–0.95 and OR 0.87, 95% CI 0.82–0.93), hospitalisation for HF (OR 0.68, 95% CI 0.61–0.77 and OR 0.87, 95% CI 0.82–0.93), and renal composite outcome (OR 0.59, 95% CI 0.52–0.67 and OR 0.86, 95% CI 0.78–0.94) compared to placebo, but SGLT-2 inhibitors reduced hospitalisation for HF (OR 0.79, 95% CI 0.69–0.90) and renal composite outcome (OR 0.69, 95% CI 0.59–0.80) more than GLP-1 RAs. The gene discussed is GLP1R; the disease is hydrops fetalis.
