## Media Hype vs. Absolute Clinical Reality (Information Gain Audit)

- **Viral Headline Claim:**
- **True Placebo-Adjusted Absolute Outcome:** Omega-3 supplementation was associated with an increased risk of incident atrial fibrillation (Hazard Ratio 1.25, 95% CI: 1.07-1.46, p = 0.013).
- **Relative vs. Absolute Statistical Breakdown:** The absolute risk increase remains low: approximately 1 extra incident AF case per 114 patients treated for 4 years at ultra-high doses (4g/day icosapent ethyl), balanced against a 25% relative reduction in ischemic cardiovascular events.
- **Funding & Sponsor Audit:** Academic Medical Center & University Heart Research Funds (Independent Academic / NIH)
- **Human Equivalent Dosing Protocol:** Dose threshold warning: limit dietary omega-3 EPA+DHA to 1000mg/day unless high-dose (2g-4g/day) is prescribed under cardiologist supervision for severe hypertriglyceridemia.
