Resource allocation for chronic stable angina: a systematic review of effectiveness, costs and cost-effectiveness of alternative interventions.

For the cost and cost-effectiveness outcomes, the authors searched the databases of MEDLINE, Health Planning and Administration, the Office of Health Economics and the NHS CRD's NHS EED. The search terms used are listed in an appendix to the review. The authors search strategy was developed using standard systematic review techniques and had five components: sources of evidence (the databases searched); inclusion and exclusion criteria for studies; methods for data extraction; data synthesis; and assessment of quality of evidence.
