How to read this. Each line is one study, summarised in plain language from its PubMed abstract, with the authors' own sentence underneath on the study page. A count of studies is not a verdict: trials differ in size, length and quality, and a result in one group of women may not hold in another. Nothing here is medical advice.
Summaries are generated, then checked by machine against the abstract they came from; any summary that could not be matched word for word was left out. Our clinical lead is reviewing the summaries topic by topic, and this note will change when that is done. Corpus last refreshed 2026-11-03. Spotted a mistake? Tell us and we will fix the summary or remove the study.
