Question Focus

Your question focus will determine what types of evidence are best. The table below outlines the possible question types and the suggested research design.

For advantages and disadvantages of each study type, see the Centre for Evidence-Based Medicine page.  

All Clinical Questions Systematic review, meta-analysis Therapy Randomized controlled trial (RCT), meta-analysis Also: cohort study, case-control study, case series Etiology Randomized controlled trial (RCT), meta-analysis, cohort study Also: case-control study, case series Diagnosis Randomized controlled trial (RCT) Also: cohort study Prevention Randomized controlled trial (RCT), meta-analysis Also: prospective study, cohort study, case-control study, case series Prognosis Cohort study Also: case-control study, case series Meaning Qualitative study Quality Improvement Randomized controlled trial (RCT) Also: qualitative study Cost Economic evaluation
