**Selected angle:** `source`

## One-sentence thesis

The cited A/B receipts support a specific working claim: reduced risk of stroke with SGLT2 inhibitors compared to non-SGLT2 inhibitors (HR, 0.83; 95%CI, 0.77-0.91); stroke (RR, 0.84 [95% CI, 0.62-1.16]; P=0.29). 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

The stroke-prevention efficacy of SGLT2 inhibitors appears risk-stratified, diverging significantly between populations with established atherosclerotic cardiovascular disease (ASCVD) and those without, suggesting a need for precision-based therapeutic targeting beyond broad diabetic indications.

Known / obvious (do not republish): SGLT2 inhibitors reduce cardiovascular events in type 2 diabetes mellitus; SGLT2 inhibitors lower blood pressure and body weight in heart failure patients

Real tension: Significant stroke reduction in type 2 diabetes with cardiovascular disease (HR 0.83, fact_id 182560) versus non-significant reduction in patients without established ASCVD (RR 0.84, fact_id 175143)

## Evidence receipts

- `fact_id=182560` (`A_core`) — reduced risk of stroke with SGLT2 inhibitors compared to non-SGLT2 inhibitors (HR, 0.83; 95%CI, 0.77-0.91) doi=10.1016/j.phrs.2021.105836

## 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

- _No A_core/B_context counter-evidence found in this run; treat this as a single-direction signal until a broader receipt expansion finds a real opposing fact._

## 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.
