Number of Patients Needed to Treat with New Diabetes Drugs to Improve Heart Health: A Meta-Analysis

AI simplified

Abstract

Meta-analysis of 13 studies with 96,860 patients shows Meta-NNTs for cardiovascular mortality of 178 for DPP-4 inhibitors, 261 for GLP-1 receptor agonists, and 118 for SGLT2 inhibitors.

  • Thirteen studies reported modest treatment benefits of GLP-1 receptor agonists and SGLT2 inhibitors for cardiovascular mortality in primary type 2 diabetes populations.
  • DPP-4 inhibitors showed a Meta- of 178, while GLP-1 receptor agonists had a Meta-NNT of 261, indicating relative treatment effects.
  • SGLT2 inhibitors demonstrated a lower Meta-NNT of 118 for cardiovascular mortality compared to other drug classes.
  • For hospitalization due to heart failure, ten studies analyzed 96,128 patients, revealing a Meta-NNT of -644 for DPP-4 inhibitors and 441 for GLP-1 receptor agonists.
  • SGLT2 inhibitors were particularly effective in primary heart failure populations, showing a Meta-NNT of 25, compared to 233 in primary diabetes populations.
