**Selected angle:** `source`

## One-sentence thesis

The cited A/B receipts support a specific working claim: Gastrointestinal adverse events were more frequent with semaglutide (82.8%) vs placebo (63.2%); Gastrointestinal events were reported in 49.1% of participants who continued subcutaneous semaglutide vs 26.1% with placebo. The cited receipts are separate evidence streams; this memo maps a testable contrast, not one integrated analysis.

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

## Why this is surprising

Real tension: the surprise is bounded to the cited receipt bundle; separate direct sources report measurable effects in adults with overweight or obesity without diabetes; patients with overweight or obesity without diabetes mellitus; adults with overweight or obesity with at least one weight-related comorbidity, without diabetes. Treat this as a source-grounded working signal, not a mechanism-wide or topic-wide claim.

## 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

## What this changes

Treat this as a focused working signal, not a broad topic claim. It moves review attention from a generic Top 5 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.
- 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

## Next extraction

- Extract independent A_core/B_context receipts that test the lead contrast directly.
- Audit whether each direct receipt remains comparable on population, endpoint, comparator, and measurement method.
