# Alpha memo: EX-MET Study: Endpoint-Specific Metformin and Exercise Findings

Hypothesis-level alpha signal; not clinical advice.

**Alpha hypothesis:** Within the EX-MET study program, direct human randomized trial analyses support a bounded negative signal across risk; treat it as hypothesis-level until the same population and endpoint are replicated.

**Core signal:**
The direct human companion analyses are randomized trial evidence for risk.
Because the recorded directions are negative, this memo treats the bundle as endpoint-specific evidence rather than a pooled clinical effect.

**Receipt-level synthesis:**
- 10.1111/dom.70478 (negative_signal): randomized trial in human; risk is negative. Metformin attenuates metabolic insulin sensitivity and insulin-stimulated carbohydrate oxidation after high-intensity exercise training in adults at risk for metabolic syndrome.. M

**Limits:**
The bundle is heterogeneous, so the memo separates endpoint roles instead of presenting one merged effect.
The EX-MET papers are companion analyses from one study program, not independent trials.
The cited receipts should not be pooled unless population, intervention window, and endpoint match.
A same-endpoint human replication would move this from alpha signal toward claim-level evidence.

**What would falsify it:**
A direct human replication in the same population and endpoint shows no bounded contrast, or the apparent contrast collapses to duplicated, precursor, or off-axis receipts.
