Systematic review of clinical effectiveness

摘要

Electronic databases were searched for published systematic reviews, RCTs, economic evaluations and ongoing research up to September 2007. The databases searched were MEDLINE, EMBASE, The Cochrane Library, Science Citation Index, the National Research Register and the UKCRN. Appendix 2 shows the databases searched and the strategy in full. Updating searches were carried out in February 2011, mainly to identify more papers from the main studies. Auto-alerts on MEDLINE were run until September 2011. Selective updating searches in MEDLINE and EMBASE were carried out in January 2012, focusing on new cost-effectiveness analyses and recent reviews.
