**Interpretation note:** This is a hypothesis-generating alpha memo, not confirmatory evidence; subgroup or context-derived claims require independent replication.

## Why this is surprising

The surprise sits inside the cited receipt bundle; separate direct sources report measurable effects in participants with overweight or obesity without type 2 diabetes; adults with overweight or obesity with at least one weight-related comorbidity, without diabetes; patients with overweight/obesity and established cardiovascular disease, without diabetes. Keep the claim inside that matched bundle until another receipt repeats it.

## Evidence Landscape

**Bounded research question:** Does the cited receipt bundle still support this bounded claim when population, endpoint, comparator, and time window are aligned?

## Evidence receipts

- `fact_id=137772` (`A_core`) — 69%-79% of participants achieved ≥10% weight loss with semaglutide 2.4 mg (vs. 12%-27% with placebo) doi=10.1111/dom.14863
- `fact_id=145389` (`A_core`) — More participants achieved weight loss ≥5% from baseline at week 104 with semaglutide (77.1%) versus placebo (34.4%; P<0.0001). doi=10.1038/s41591-022-02026-4
- `fact_id=149514` (`A_core`) — semaglutide (1.8%) versus placebo (2.2%) doi=10.1038/s41591-024-03015-5
- `fact_id=167544` (`A_core`) — subcutaneous semaglutide is effective for weight loss with an 11.85% reduction from baseline compared to placebo. doi=10.15605/jafes.037.02.14
- `fact_id=144494` (`A_core`) — At 208 weeks, semaglutide was associated with mean reduction in weight (-10.2%) versus placebo (-1.5%; P < 0.0001). doi=10.1038/s41591-024-02996-7

## Context receipts

_Boundary evidence only; these receipts broaden source context but do not independently prove the lead claim._

- `fact_id=149782` (`A_core`) — semaglutide induced a significant body weight loss (MD: -10.09%; 95% CI: -11.84 to -8.33; p ˂ 0.00001) doi=10.3389/fphar.2022.935823

## What this changes

Treat this as a focused working signal, not a broad topic claim. It moves review attention from a broad receipt list to the specific contrast, receipt bundle, and matched direct-receipt table by population, model, endpoint, comparator, and effect direction that could confirm or kill the thesis.

## Limitations

- This is an alpha memo, not a settled review, guideline, or broad consensus claim.
- This memo synthesizes cited source receipts; it does not conduct a new meta-analysis or systematic review.
- Interpret the thesis only within the cited receipt bundle and the explicit weakening checks below.
- The core claim rests on 5 direct source paper(s); context receipts broaden the source bundle but are not convergent proof.
- Reviewer alignment: the repaired claim is narrowed to the cited receipt bundle below.
- Independent receipts fail to reproduce the claimed contrast.
- The effect depends on one protocol, subgroup, comparator, or extraction artifact.

## What would weaken this

- Independent receipts fail to reproduce the claimed contrast.
- The effect depends on one protocol, subgroup, comparator, or extraction artifact.

## Strongest counter-evidence

- `fact_id=137771` (`A_core`) — semaglutide 2.4 mg was associated with mean weight losses of 14.9%-17.4% in individuals with overweight or obesity without type 2 diabetes from baseline to week 68 Source: Semaglutide for the treatment of overweight and obesity: A review
- `fact_id=143885` (`A_core`) — In participants not taking SGLT2i at baseline, hazard ratio 0.73 (95% confidence interval: 0.63, 0.85; P < 0.001). Source: Effects of semaglutide with and without concomitant SGLT2 inhibitor use in participants with type 2 diabetes and chronic kidney disease in t
