Editorial disclaimer
How to use our research summaries.
Research needs context
A paper's findings depend on its methods, participants, doses and duration. They may not apply to you or represent the wider evidence. Research can be preliminary, disputed, corrected or retracted.
Read the original source
Our summaries simplify research and may omit details or contain errors. They do not replace the original paper or a review of the wider evidence. Check important details in the linked source, including limitations and disclosures. Most summaries are written from the paper's abstract rather than its full text.
Make treatment decisions with a professional
Consult a qualified healthcare professional before starting, stopping or changing treatment. Do not disregard or delay professional medical advice because of something you read here. If you have a medical emergency, contact your local emergency services.
Citations are not endorsements
A summary is a description of what a paper reported — not an endorsement of the paper, its authors, or any treatment it discusses. Likewise, being cited here doesn’t mean a researcher, journal or product endorses this site.
Help us correct errors
Use “Report an error in this summary” under any study summary to flag a factual mistake, a missing qualification or a source error. Quote the passage, say what it should say, and link a supporting source where possible.
