Understanding medical information
Study limitations
Small groups, short timelines, and narrow populations limit what results mean for you.
Screening versus diagnosis
A screening result flags possible concern. Diagnosis needs clinical evaluation.
Relative versus absolute risk
Ask for the actual numbers. A big percent change can still be a small risk.
When information raises a personal concern, discuss it with a clinician.
