Evidence library
Science Library
A practical guide to asking better questions about health research: define the claim, inspect the source, notice uncertainty, and bring personal decisions back to a qualified clinician.
A four-part reading habit
1. Define the question
What exact claim, outcome, population, intervention, and timeframe are being discussed?
2. Inspect the source
Is the source a guideline, systematic review, controlled trial, observational study, mechanism, or opinion?
3. Notice uncertainty
What limitations, tradeoffs, missing comparisons, and unanswered questions change the conclusion?
4. Return to context
How might your history, goals, alternatives, and preferences affect the clinical conversation?
