Field notes
The register separates a verdict—such as “raises risk” or “no link found”—from the rung assigned to the evidence, and cautions that certainty does not mean a large effect. The homepage organizes options across five rungs and links out to topic pages, including cancer-specific screening and treatment paths. It reports a review date of 31 October 2026 and describes an exercise section with a weekly-target calculator.
