Subgroup analyses of the total population according to the diabetes status showed that SGLT2 inhibitors significantly reduced the risk of hospitalisation for HF (HR: 0.68; 95% CI: 0.61, 0.75; I2: 0%), as well as the risk of hospitalisation for HF or CV death (HR: 0.72; 95% CI: 0.66, 078; I2: 0%) and CV death (HR: 0.82; 95% CI: 0.74, 0.91; I2: 0%). The gene discussed is SLC5A2; the disease is hydrops fetalis.
