Every summary on this site uses the same five-part structure: the research question, what the evidence suggests, what the evidence doesn't prove, practical interpretation, and sources. The aim is to describe research, not to recommend treatment.

How to read these summaries

These summaries translate the findings of systematic reviews, clinical trials, and clinical guidelines into plain English. They're structured to separate what population-level evidence shows from what it can't prove for any individual patient. They're educational resources, not medical advice.
