Meta-analysis is the statistical technique by which data from a number of independent studies of the same topic are combined in order to determine the best estimate of the overall result from those studies. It can be applied to most types of epidemiological study (e.g. observational or case-control studies) but is most often used to combine the results of randomised controlled trials within the context of a systematic review (i.e. a review which outlines its methods to minimize bias and chance). A systematic review that includes a meta-analysis is often called a quantitative systematic review whereas one that does not may be called qualitative.
