All physicians are familiar with the type of general review articles found in many medical journals. Systematic reviews are different. They apply a strict, scientific methodology to the reviewing process to produce a review that is comprehensive, reliable, and as free from bias as possible. As a result, systematic reviews occupy the highest position in the "levels of evidence" tables associated with the practice of evidence-based health care. Systematic reviews relevant to surgery are no less relevant than systematic reviews in other areas of health care. They should be a prerequisite of any new research, a key component in decision making, and an opportunity for all surgical practitioners to get involved in the conduct and interpretation of research.
