Further statistics in dentistry Part 8: Systematic reviews and meta-analyses

Br Dent J. 2003 Jan 25;194(2):73-8. doi: 10.1038/sj.bdj.4809877.


A systematic review of research evidence is an efficient approach to integrating existing information, invariably a multiplicity of published articles, with a view to establishing whether the scientific findings are consistent. If so, it may be possible to draw conclusions and make recommendations about treatment regimens or observed effects which have greater credence than those obtained from individual studies. The systematic review relies on a specified checklist which determines which articles should be included in the review, and how each should be critically appraised to provide relevant information relating to the focus of the review.
