Evidence Map

What The Sources Report

• Affecting 1 in 9 Americans aged older than 45 years, SCI is associated with mental distress and poses a risk for dementia. [Sarvestan Javad (2025); evidence level 2]
• Even though the polygenic risk score did not differ between those with subjective cognitive decline and those without it, the former had more than double the risk of developing dementia (hazard ratio 2.14, 1.44-3.18). [Sarvestan Javad (2025); evidence level 2]
• Managing risk factors through healthy eating habits and regular exercise is crucial for CVD prevention. [Lee Yu Geon (2026); evidence level 3]
• Unsaturated fatty acids found in olive oil and nuts can help prevent CVDs by regulating cholesterol metabolism. [Lee Yu Geon (2026); evidence level 3]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

There is trial evidence in the current set, but population and intervention details still matter. For dark chocolate cognition randomized trial, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
