Editorial policy

• A clinician reviews every guide before we mark it as reviewed.
• Every guide shows the reviewer's name and the review date.
• We review every guide at least once a year.
• Every guide lists its sources.
• Sponsors cannot commission, edit or stop a guide.
• We write in plain words. We explain each medical term.

Draft guides

A guide without a reviewer shows a "Draft: awaiting clinical review" banner. Treat a draft with care.
