Appraising prognosis evidence
Assess patient similarities, follow-up period, adjustment, temporality, and precision of outcomes
After reading the article related to prognosis, ask these questions:
1. Was a defined, representative sample of patients assembled at a common point in the course of their disease?
2. Was the follow-up of study patients sufficiently long and complete?
3. Were objective outcome criteria applied in a blind fashion?
4. If subgroups with different prognoses are identified, was there adjustment for important prognostic variables and validation in an independent group of test subjects?
5. How likely are the outcomes over time?
6. How precise are the prognostic estimates?
