The context receipts provide source breadth and boundary checks, not independent confirmation of the lead claim.\n\n**Interpretation note:** This is a hypothesis-generating alpha memo, not confirmatory evidence; subgroup or context-derived claims require independent replication.\n\n## Why this is surprising\n\nReal tension: the useful signal is narrower than the topic label. The lead receipts support the core claim, while the added A/B context receipts define where that claim may generalize, fail, or need a separate extraction.\n\n## Evidence receipts\n\n- `fact_id=140174` (`A_core`) — Supplementation was associated with reduced risk of MI (relative risk [RR], 0.87; 95% CI, 0.80 to 0.96), high certainty NNT of 272 doi=10.1016/j.mayocp.2020.08.034\n- `fact_id=140175` (`A_core`) — but not CVD events (RR, 0.95; 95% CI, 0.90 to 1.00) doi=10.1016/j.mayocp.2020.08.034\n- `fact_id=140176` (`A_core`) — CHD events (RR, 0.90; 95% CI, 0.84 to 0.97), high certainty NNT of 192 doi=10.1016/j.mayocp.2020.08.034\n- `fact_id=138000` (`A_core`) — Participants who received omega-3 were 700 (65.06%) compared to 376 (34.94%) who received a placebo. doi=10.7759/cureus.30091\n- `fact_id=185966` (`A_core`) — Comparing the highest to the lowest quintiles, individuals had 31% (95% CI, 10–55%) higher CVD mortality doi=10.7554/elife.90132.3\n- `fact_id=185965` (`A_core`) — Comparing the highest to the lowest quintiles, individuals had 14% (95% CI, 0–31%) higher cancer mortality doi=10.7554/elife.90132.3\n- `fact_id=185964` (`A_core`) — Comparing the highest to the lowest quintiles, individuals had 26% (95% CI, 15–38%) higher total mortality doi=10.7554/elife.90132.3\n- `fact_id=1138` (`A_core`) — little or no effect of increasing LCn3 on all-cause mortality (risk ratio (RR) 0.97, 95% CI 0.93 to 1.01 doi=10.1002/14651858.cd003177.pub5\n- `fact_id=178493` (`A_core`) — the 3 treatments combined showed a significant 39% decreased odds of becoming prefrail compared to the control doi=10.1093/gerona/glad073\n\n## Context receipts\n\n_Boundary evidence only; these receipts broaden source context but do not independently prove the lead claim._\n\n- `fact_id=143791` (`B_context`) — doses of 4 g/day (instead of the more common <1 g/day) doi=10.1007/s11936-016-0487-1\n- `fact_id=94952` (`B_context`) — omega-3 fatty acid supplements at more than 2 g/day may contribute to muscle mass gain (0.67 kg; 95% CI: 0.16, 1.18) doi=10.3390/nu12123739\n\n## What this changes\n\nTreat 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.\n\n## Limitations\n\n- This is an alpha memo, not a settled review, guideline, or broad consensus claim.\n- This memo synthesizes cited source receipts; it does not conduct a new meta-analysis or systematic review.\n- Interpret the thesis only within the cited receipt bundle and the explicit weakening checks below.\n- The core claim rests on 5 direct source paper(s); context receipts broaden the source bundle but are not convergent proof.\n- Independent receipts fail to reproduce the claimed contrast.\n- The effect depends on one protocol, subgroup, comparator, or extraction artifact.\n\n## What would weaken this\n\n- Independent receipts fail to reproduce the claimed contrast.\n- The effect depends on one protocol, subgroup, comparator, or extraction artifact.\n\n## Strongest counter-evidence\n\n- `fact_id=1138` (`A_core`) — little or no effect of increasing LCn3 on all-cause mortality (risk ratio (RR) 0.97, 95% CI 0.93 to 1.01 Source: Omega-3 fatty acids for the primary and secondary prevention of cardiovascular disease\n\n## Next extraction\n\n- Extract independent A_core/B_context receipts that test the lead contrast directly.\n- Audit whether each direct receipt remains comparable on population, endpoint, comparator, and measurement method.\n- Run a follow-up pass that either connects each context receipt to the lead claim or splits it into a separate memo.\n","metadata":{"abstract":"The direct receipts support a narrow working claim: Supplementation was associated with reduced risk of MI (relative risk [RR], 0.87; 95% CI, 0.80 to 0.96), high certainty NNT of 272; but not CVD events (RR, 0.95; 95% CI, 0.90 to 1.00).
