Where does the SDE research come from?

The SDE deep dives and Q&A Hub are grounded in the primary literature of cardiovascular medicine: the New England Journal of Medicine, Journal of the American College of Cardiology, Circulation, JAMA, JAMA Cardiology, Lancet, and the major subspecialty journals (Hypertension, European Heart Journal, Journal of the American Heart Association). All claims rated Solid (1) or Promising (2) are cited to a specific trial, cohort study, or guideline document, with the citation inline in the text rather than in a footnote section where they can be ignored.

The VOC (voice of customer) research that shapes the question framing comes from systematic analysis of forums where men discuss their health, r/whoop, r/AskMenOver40, r/diabetes_t2, r/biohackers, and similar communities where the language of fear and confusion is documented in the original words rather than translated through clinical summary. The forum quotes that appear in deep dive opening sections are real, documented expressions of the specific questions this content is designed to answer.

What to do: Verify any claim that matters to your clinical decision-making by following the inline citation to the primary source. The citation format is designed to make verification straightforward.
