Evidence Policy

This project is not a medical guideline. But when it discusses red flags, screening, chronic markers, mental health crisis, medication boundaries, or family decisions about care, the boundaries must be calibrated against credible public sources.

Evidence priority:

1. Official agencies and clinical guidelines;
2. Professional society guidelines or consensus statements;
3. Systematic reviews and meta-analyses;
4. High-quality randomized controlled trials;
5. Large cohort studies;
6. Expert explanations, courses, and books;
7. Personal experience and examples.

Writing rules:

• High-risk judgments must be supported by authoritative sources.
• Numeric thresholds must identify the source and review date when they are used.
• If guidance may change, write "as of YYYY-MM" or an equivalent review date.
• A single news story or single new study can be a clue, but should not directly rewrite the book's conclusion.
• Uncertain or contested areas should state uncertainty and avoid definitive personal advice.
