Systematic Reviews and Meta-Analyses
Authors of systematic reviews ask a specific clinical question, perform a comprehensive search of the literature, eliminate poorly done studies and make practiced recommendations based on the well-done studies.
A meta-analysis is a systematic review that combines the results of all the studies into one statistical analysis of results.
Critically Appraised Topics
Authors evaluate and synthesize multiple research studies.
Critically Appraised Individual Articles
Authors evaluate individual research studies.
Address a focused clinical question where review authors systematically search for, identify, select, summarize and critically apraise all of the medical research literature available on a specific topic. Statistical techniques may be used to combine the results of these studies. The authors clearly state the search methods used to locate these studies. It is important to examine the search methods used and decide for yourself if it was broad enough to include all of the relevant studies, and if the studies found were relevant to the clinical question.
Randomized Controlled Clinical Trial (RCT)
An experimental design used for testing the effectiveness of a new medication or a new therapeutic procedure. Individuals are assigned randomly to a treatment group or a control group, and the outcomes are compared. RCT is the most accepted scientific method of determining the benefit of a drug or a therapeutic procedure. It represents the best evidence available, which is integrated into the final decision about the management of a condition by healthcare practitioners in what is called evidence-based healthcare.
an experiment performed on human beings in order to evaluate the comparative efficacy of two or more therapies.
In the Cochrane Library database, the protocol outlines the question that the review authors are addressing, detailing the criteria against which studies will be assessed for inclusion in the review, and describing how the authors will manage the review process.
When results of individual studies are combined to produce an overall statistic.
Brings together information about previously published research on a topic. It provides a critical appraisal of the topic over a period of time. It is helpful in identifying the important literature on a topic. Given the vast amount of scientific literature published, review articles are an excellent tool for researchers wishing to research a topic.
