AbstractSystematic reviews and meta-analyses are techniques of data retrieval and analysis which complement traditional narrative reviews. They are widely used in clinical medicine and are finding an increasing role in anatomical pathology. Performing high quality systematic review and meta-analysis requires the accumulation of large numbers of cases from well planned and executed studies and is facilitated if data is presented in a standardized manner. Techniques which allow data from individual patients included in a variety of different studies are now being developed indicating that in future research papers may require a more detailed description of results than in the past. This need may be met by posting anonymised data on the Internet. Systematic reviews and meta-analyses are never complete since data are continually contributed and analyses constantly updated. As with any research paper, the results of these techniques require careful evaluation and the role of the expert reviewer is enlarged by these methodologies.
