JSTOR is a collection of core scholarly journals in the humanities, social sciences, and sciences digitized in most cases back to the first date of issue. Includes selected books, primary sources and other materials for academic work.
Systematic reviews ask a specific clinical question, perform a comprehensive literature search, eliminate the poorly done studies and attempt to make practice recommendations based on the well-done studies. A meta-analysis is a systematic review that combines all the results of all the studies into a single statistical analysis of results.
Critically-appraised individual articles evaluate and synopsize individual research studies, while critically-appraised topics evaluate and synthesize multiple research studies.
Case control studies looks at two groups retrospectively--one with the condition and one without-- to determine causes and natural history. Cohort studies are longitudinal studies that follow two groups (a control group and a group the condition of intervention of interest) over time. Randomized controlled double blind studies are the gold standard for medical evidence.
