Tirzepatide versus Semaglutide effects on blood sugar and weight in people with type 2 diabetes

Updated

Abstract

Essence

Tirzepatide initiation was associated with larger 12-month HbA1c and weight reductions than injectable semaglutide in adults with type 2 diabetes.

Evidence

Retrospective propensity-matched database analysis compared GLP-1 RA-naive and non-naive adults with T2D starting tirzepatide or injectable semaglutide from 2022 to 2023.

Caveat

Only patients with HbA1c and weight recorded at both time points contributed outcomes, so residual confounding and missing-data selection remain possible.
