How a study becomes advice

  1. 01 · Collect

    We gather peer-reviewed papers from Europe PMC, which includes PubMed and Cochrane reviews.

  2. 02 · Weigh

    Each paper is tagged by study design. Cochrane reviews and meta-analyses count more than single studies.

  3. 03 · Check

    Retracted papers are removed for good, and every source keeps its DOI or PMID so you can check it.

  4. 04 · Grade

    Advice is published only with citations and an A–D grade, worded the way the studies report it.
