Tirzepatide treatment in adults with obesity but without pre-existing type 2 diabetes significantly reduces the incidence of new-onset type 2 diabetes compared to semaglutide.

If you have obesity and are at risk for type 2 diabetes, tirzepatide may be a more effective option than semaglutide for preventing the onset of the disease. This is based on real-world data showing a 27% lower risk of developing type 2 diabetes with tirzepatide compared to semaglutide over a one-year follow-up period. Consult your doctor to see if this treatment is appropriate for you.

Tirzepatide was associated with both lower risk for incident T2D (HR 0.73, 95% CI 0.58–0.92, p < 0.001)... compared to semaglutide

Why this rating

Large retrospective cohort study (n=13,846) with propensity score matching, but observational design limits causal inference compared to RCTs.
