There were significantly fewer hospitalizations for HF (OR: 0.70, 95%CI: 0.64–0.76), cardiovascular deaths (OR:0.86, 95%CI: 0.77–0.97) and all-cause deaths (OR:0.90, 95%CI: 0.82–0.98) in the SGLT2 inhibitors group compared to the placebo group, without any interaction with BMI group (test for subgroup differences: x2 = 1.79, p = 0.62; x2 = 0.27, p = 0.97; x2 = 0.39, p = 0.94, respectively). This evidence concerns the gene SLC5A2 and hydrops fetalis.
