Evidence Scores are computed mechanically from the published research (PubMed / Semantic Scholar / OpenAlex): study design, participant numbers, and consistency across studies. An LLM is used only to extract study data, never to decide a score.

This is research-based information, not medical advice, and not a diagnosis. Consult a qualified professional about your own situation.
