Abstract
Tirzepatide provides superior efficacy in weight reduction and metabolic control compared to existing therapies. The present systematic review assessed the effect of Tirzepatide on the risk of developing type 2 diabetes mellitus (T2DM) among people living with obesity or overweight. Six major databases [MEDLINE (PubMed), ClinicalTrials.gov, EMBASE, Scopus, Web of Science and Cochrane Library] were searched for potential studies published till 10 July 2025. Two-stage dual screening with third-person adjudication was adopted for screening of studies. PROSPERO ID: CRD42024614466. RoB 2.0 and the Newcastle-Ottawa Scale were used to assess the quality of randomised controlled trials (RCTs) and cohort studies, respectively. Database search yielded 2601 studies, among which three studies were eligible (one RCT and two cohort studies) for systematic review. The hazard ratio (HR) for the new-onset diabetes at 12 months following the Tirzepatide intake was significantly lower than that of the Semaglutide group of patients (HR = 0.73, p < 0.001 [95% CI: 0.58-0.92]). The risk of the new-onset diabetes for 176 weeks (HR = 0.07, p < 0.001 [95% CI: < 0.01-0.1]) and 193 weeks (HR = 0.12, p < 0.001 [95% CI: 0.1-0.2]) following the Tirzepatide intake was significantly lower than that of the placebo group of patients. Tirzepatide might have significant efficacy in the prevention of T2DM in patients with obesity or overweight.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
