Abstract

Background To investigate the efficacy of SGLT2 inhibitors on multiple cardiorenal outcomes across different racial/ethnic groups and regions.Methods We searched PubMed, Cochrane Library, Web of Science, and Embase databases in April 2024 for a systematic review and meta-analysis. Owing to inconsistencies in the reporting of the racial/ethnic and regional demographics, participants were grouped into three racial groups (Asian, Black, and White) and four regional (Asia, Central/South America, Europe, North America) groups. We compared the efficacy of SGLT2 inhibitors among these racial/ethnic and regional groups by calculating the ratio of hazard ratios (RHR). We evaluated the composite of cardiovascular death or hospitalization for heart failure (HHF), cardiovascular death, HHF, all-cause death, major adverse cardiac events, and cardiorenal composite outcomes.Results We included 14 randomized placebo-controlled trials with 94,445 participants. Across the three racial/ethnic groups, SGLT2 inhibitors showed comparable efficacy. Compared with White patients, the efficacy of SGLT2 inhibitors on HHF was more pronounced in Black patients (RHR, 0.64; 95 % confidence interval [CI], 0.44-0.94), and a numerically lower risk was associated with Asian patients (RHR, 0.62; 95 % CI, 0.38-1.01). A consistent reduction in cardiovascular events with SGLT2 inhibitors was observed across all regions, while the efficacy of SGLT2 inhibitors on HHF was more pronounced in Asia than in other regions (RHR, 0.52; 95 % CI, 0.33-0.81).Conclusions SGLT2 inhibitors showed generally consistent efficacy across various racial/ethnic and regional groups, with some differences noted in specific populations. Ensuring adequate representation of diverse populations in clinical trials would be key to addressing healthcare disparities.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
