Description

These tools teach users to critically appraise different types of evidence. The program consists of seven critical appraisal tools to assess:

  1. Systematic reviews
  2. Randomized controlled trials (RCTs)
  3. Qualitative research
  4. Economic evaluation studies
  5. Cohort studies
  6. Case-control studies
  7. Diagnostic test studies

Steps for Using Method/Tool

Each tool systematically guides users through questions in three main sections:

  1. Is the study valid?
  2. What are the results?
  3. Will the results help locally?
