Number Needed to Treat with Semaglutide for People with Overweight or Obesity and Heart Disease but No Diabetes

AI simplified

Abstract

The (NNT) for semaglutide to prevent major adverse cardiovascular events significantly decreased from 125 at 1 year to 58 at 4 years.

  • Relative risk reductions for major adverse cardiovascular events (MACE) were observed at 20% for both primary and extended NNTs and 41% for the broader outcomes.
  • NNT estimates decreased when including additional outcomes such as hospitalization and kidney health, indicating a broader treatment benefit.
  • At 4 years, the NNT for the extended outcomes was 11, suggesting a more favorable treatment effect over time.
  • These findings indicate that evaluating semaglutide's effects beyond the primary endpoint may provide greater value for stakeholders.
