“…In recent years, more and more real-world studies have revealed the obvious benefits of SGLT2 inhibitors against many respiratory diseases, such as chronic obstructive pulmonary disease (COPD) (Pradhan et al, 2022), pneumonia (Wu et al, 2022), obstructive airway disease (Au et al, 2023), pulmonary edema (Jeong et al, 2023), and respiratory failure (Jeong et al, 2023). Similar with these real-world evidences, several meta-analyses (Yin et al, 2021;Li et al, 2022;Wang et al, 2022;Wang and Zhou, 2024;Xiao et al, 2024) based on RCTs have also revealed the respiratory system benefits of SGLT2 inhibitors. A meta-analysis (Yin et al, 2021) of 9 RCTs showed that use of gliflozins was significantly associated with the lower risks of multiple respiratory diseases, such as COPD, and asthma.…”
