Therefore, the Cochrane Handbook says "it may still be worthwhile for reviewers to search MEDLINE using the Cochrane highly sensitive search strategy and to obtain and check the full reports of possibly relevant citations" . There is a validated filter in the Cochrane Handbook for both PubMed and Ovid interfaces1. or randomization/ or intermethod comparison/ or placebo.ti,ab. Two strategies are offered: a sensitivity-maximizing version and a sensitivity- and precision-maximizing version. It is recommended that searches for trials for inclusion in Cochrane reviews begin with the sensitivity-maximizing version in combination with a highly sensitive subject search. Using search filters: Highly desirable Use specially designed and tested search filters where appropriate including the Cochrane Highly Sensitive Search Strategies for identifying randomized trials in MEDLINE, but do not use filters in pre-filtered databases e.g. Background: The Cochrane Highly Sensitive Search Strategy (HSSS), which contains three phases, is widely used to identify Randomized Controlled Trials (RCTs) in MEDLINE. Objective: To develop, through revision of the Cochrane Collaboration search strategy for OVID-MEDLINE, a highly sensitive search strategy to retrieve reports of controlled trials using PubMed.

The Cochrane Collaboration publishes an extensive handbook for systematic reviews. We developed a highly sensitive search strategy for the retrieval of reports of controlled trials for use with PubMed that retrieves more relevant citations (greater sensitivity) and fewer non-relevant citations (greater precision) than the original Cochrane search strategy.

The Cochrane Highly Sensitive Search Strategy (HSSS) identified 80% of the total number of reports of randomized trials found, searches categorised as 'complex' (including the Cochrane HSSS) found 65% and 'simple' found 42%. MeSH terms for kidney disease were combined with MeSH terms and text words for erythropoietin therapy. Cochrane ENT will use the highly sensitive search strategy designed by Cochrane for identifying randomised controlled trials and controlled clinical trials (as described in the Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0, Box 6.4.b). The Associate found the literature about searching PubMed for RCTs to use in systematic reviews to be most useful and built upon the Cochrane Highly Sensitive Search Strategy for Identifying Randomized Trials in MEDLINE. The ISSG Search Filters Resource provides validated search filters for many other study design types. Due to NLM changes the terms have been amended: o 'animal' check tag - 'animal' was amended to 'animals' MeSH term (January 2004) RCT_CCT Cochrane_Ovid Embase-09_2020 (1) - Google Docs.
