Question Domain & Evidence Pyramid

Remember, certain study designs offer stronger evidence for different types of research questions (and guide you toward the best questions for appraisal.) The most common question domains are therapy, diagnosis, prognosis, & etiology.

A meta-analysis, systematic review, or practice guideline that synthesizes multiple studies of the most appropriate study design can be even stronger evidence when relevant to your question, patient, outcomes, and inclusion/exclusion criteria.
