"A review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyse data from the studies that are included in the review. Statistical methods (meta-analysis) may or may not be used to analyse and summarise the results of the included studies."
"Systematic reviews identify, select, assess, and synthesize the findings of similar but separate studies. They can help clarify what is known and not known about the potential benefits and harms of drugs, devices, and other healthcare services. But the quality of systematic reviews varies; often the scientific rigor of the collected literature is not scrutinized or there are errors in data extraction and meta-analysis."
"A systematic review is a summary of the clinical literature. A systematic review is a critical assessment and evaluation of all research studies that address a particular clinical issue. The researchers use an organized method of locating, assembling, and evaluating a body of literature on a particular topic using a set of specific criteria. A systematic review typically includes a description of the findings of the collection of research studies. ==> The systematic review may also include a quantitative pooling of data, called a meta-analysis.
Example: Scientists collected all the published studies that compared types of treatment for prostate cancer that had not spread beyond the prostate gland. They compiled the results of these studies in a comparative effectiveness review, which is a type of systematic review."
