Tirzepatide 10 and 15 mg versus semaglutide 2.4 mg in people with obesity or overweight with type 2 diabetes: An indirect treatment comparison.
Trial report in Diabetes, obesity & metabolism, 2025. The graph read 6 numbers from its abstract, feeding 2 cells of the map, but none could be read as for or against, so it casts no vote. It also reports an association that does not count as treatment evidence, such as OR 1.76 (1.04 to 2.97) for weight reduction ≥5%. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

Tirzepatide 15 mg had significantly higher odds of achieving ≥5% weight reduction (odds ratio 15 mg: 1.76, 95% CI 1.04-2.97, p = 0.035; odds ratio 10 mg: 1.24, 95% CI 0.75-2.04, p = 0.407), and both tirzepatide doses were associated with significantly greater reductions in HbA1c (%) levels (mean difference, 10 mg: 0.47%; 15 mg: 0.56%, p < 0.001) than semaglutide.

For every cell the paper feeds: the belief in the claim with and without this paper, and this paper's estimate drawn against every other readable study in the cell. The ringed dot is this paper.

The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The marked sentences are the ones the graph read a number from.
aimsTirzepatide and semaglutide demonstrated clinically meaningful weight reduction in people with obesity or overweight and type 2 diabetes (T2D) in SURMOUNT-2 and STEP 2 clinical trials, respectively. In the absence of head-to-head trials, this study compared the efficacy of tirzepatide 10 and 15 mg with semaglutide 2.4 mg using an indirect treatment comparison. MATERIALS AND
methodsMean percent change in weight from baseline, weight reduction ≥5% and mean change in glycated haemoglobin (HbA1c [%]) were compared between tirzepatide 10/15 mg (week 72, SURMOUNT-2) and semaglutide 2.4 mg (week 68, STEP 2) applying the Bucher method to the efficacy estimand. Sensitivity analyses included the use of matching-adjusted indirect comparison, treatment regimen estimand and comparing study outcomes at 68 weeks.
resultsTirzepatide 10 and 15 mg were associated with significantly greater mean percent weight reductions versus semaglutide (mean difference, 10 mg: 2.57%; 15 mg: 4.79%, p < 0.01). Tirzepatide 15 mg had significantly higher odds of achieving ≥5% weight reduction (odds ratio 15 mg: 1.76, 95% CI 1.04-2.97, p = 0.035; odds ratio 10 mg: 1.24, 95% CI 0.75-2.04, p = 0.407), and both tirzepatide doses were associated with significantly greater reductions in HbA1c (%) levels (mean difference, 10 mg: 0.47%; 15 mg: 0.56%, p < 0.001) than semaglutide. Sensitivity analyses were generally consistent with the primary analysis, exceptions including when power was reduced in the matching-adjusted indirect comparison analyses and in the categorical weight reduction outcome.
conclusionsThis analysis suggested greater reductions in bodyweight and HbA1c (%) levels associated with tirzepatide 10 and 15 mg than with semaglutide 2.4 mg in people with obesity or overweight and T2D.
