**Selected angle:** `source`

## One-sentence thesis

The cited direct receipts support a bounded 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.

**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 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; patients with type 2 diabetes and established CV disease or CV risk factors. Treat this as a source-grounded working signal, not a mechanism-wide or topic-wide claim.

## Evidence Landscape

_Evidence-map boundary: cited receipts are separate evidence streams unless an integrated analysis is explicitly stated; this memo maps a testable contrast, not a pooled meta-analysis or settled conclusion._

**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=161900` (`A_core`) — Gastrointestinal adverse events were more frequent with semaglutide (82.8%) vs placebo (63.2%) source=Effect of Subcutaneous Semaglutide vs Placebo as an Adjunct to Intensive Behavioral Therapy on Body Weight in Adults Wit
- `fact_id=158054` (`A_core`) — Gastrointestinal events were reported in 49.1% of participants who continued subcutaneous semaglutide vs 26.1% with placebo source=Effect of Continued Weekly Subcutaneous Semaglutide vs Placebo on Weight Loss Maintenance in Adults With Overweight or O
- `fact_id=100298` (`A_core`) — serious adverse events were not statistically significant: OR of 1.06 (p = 0.82) doi=10.1111/obr.13792
- `fact_id=140867` (`A_core`) — fewer first major adverse CV events with semaglutide vs. placebo, with HRs of 0.74 (95% CI 0.58-0.95) doi=10.3389/fendo.2021.645566
- `fact_id=137451` (`A_core`) — Compared with placebo, the use of semaglutide was associated with substantial decreases in long-term relative (WMD -12.1%, 95% CI -13.5 to -10.7) and absolute body weight doi=10.1016/j.amjcard.2024.04.041

## Context receipts

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

- `fact_id=75386` (`A_core`) — a greater proportion treated with semaglutide were normoglycemic (69.5% vs. 35.8%; P < 0.0001) doi=10.2337/dc24-0491

## What this changes

_Interpretation boundary: this is a hypothesis-generating alpha map, not confirmatory evidence or a settled conclusion. The heterogeneity matters because it routes the next test to the specific population, endpoint, comparator, and time window that can replicate, rather than letting a broad topic-level effect claim leak across mismatched receipts._

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.
- 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=100298` (`A_core`) — serious adverse events were not statistically significant: OR of 1.06 (p = 0.82) Source: Efficacy and safety of once‐weekly subcutaneous semaglutide on weight loss in patients with overweight or obesity without diabetes mellitus—
