Key Result

Combination therapy with SGLT-2 inhibitors and GLP-1 RAs was associated with lower all-cause mortality compared to SGLT-2 inhibitors alone in type 2 diabetes.

Key Points

  • The study aims to assess the effectiveness of combination therapy with SGLT-2 inhibitors and GLP-1 RAs compared to SGLT-2 inhibitors alone in individuals with type 2 diabetes.
  • Analyzed a large real-world cohort of individuals with type 2 diabetes
  • Compared all-cause mortality and cardiorenal outcomes between therapy groups
  • Controlled for potential confounding factors in statistical analyses
  • Combination therapy was associated with a lower hazard of all-cause mortality
  • Most secondary cardiorenal outcomes showed favorable estimates, though imprecise
  • Findings indicate significant clinical benefits of using both drug classes together

Structured PICO

Does combination therapy with SGLT-2 inhibitors and GLP-1 RAs reduce all-cause mortality compared with SGLT-2 inhibitors alone in individuals with type 2 diabetes?

In a real-world cohort of patients with type 2 diabetes, concurrent use of SGLT-2 inhibitors and GLP-1 RAs was associated with lower all-cause mortality compared to SGLT-2 inhibitor therapy alone.

Limitations

  • Residual confounding cannot be fully excluded
  • Imprecise estimates for secondary cardiorenal outcomes

Abstract

In this large real-world cohort, combination therapy with SGLT-2 inhibitors and GLP-1 RAs was associated with a lower hazard of all-cause mortality, while most secondary cardiorenal outcomes showed generally favourable but imprecise estimates. These findings suggest that sustained concurrent use of both drug classes may offer meaningful clinical benefits in routine practice, although residual confounding cannot be fully excluded.
