Abstract

fetched live from OpenAlex

Background: In patients at elevated cardiovascular risk, statins reduce the occurrence of ischemic stroke. However, residual stroke risk persists. Methods: REDUCE-IT, a multinational, double-blind trial, randomized 8179 statin-treated patients with controlled low-density lipoprotein cholesterol, elevated triglycerides, and risk for, or evidence of, atherosclerosis to icosapent ethyl (IPE), a purified, stable ethyl ester of eicosapentaenoic acid (4 grams/day), or placebo. IPE reduced the primary composite endpoint (CV death, myocardial infarction (MI), stroke, coronary revascularization, hospitalization for unstable angina) and the key secondary composite endpoint (CV death, MI, stroke) by 25% and 26%, respectively, (each p<0.000001). Total (first and recurrent) ischemic events were reduced by 32% (p<0.000001). We examined additional prespecified and post hoc stroke endpoints. Results: Event rates for time to first fatal or nonfatal stroke were 2.4% vs. 3.3% for IPE vs. placebo; hazard ratio (HR) (95% CI) = 0.72 (0.55-0.93); P=0.01; the relative risk reduction (RRR) was 28%, absolute risk reduction (ARR) 0.9%, and number needed to treat (NNT) 114. For every 1,000 patients treated for 5 years with IPE, approximately 14 strokes (fatal or nonfatal) were averted; rate ratio (RR) (95%CI) = 0.68 (0.52-0.91); P=0.008 (Figure). Ischemic stroke time to first event rates were 2.0% vs 3.0% for IPE vs placebo a 36% reduction [HR=0.64 (0.49-0.85); P=0.002]. Hemorrhagic stroke occurred at low rates with no significant difference for IPE vs. placebo (0.3% vs 0.2%; P=0.55). Conclusions: In REDUCE-IT, icosapent ethyl significantly reduced the risk of ischemic stroke, with no excess in hemorrhagic stroke, in statin-treated patients with elevated triglycerides and atherosclerosis or diabetes.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
