2.3 Search strategy
Potential studies were identified by searching electronic databases of MEDLINE, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials (CENTRAL), International Pharmaceutical Abstracts, ClinicalTrials.gov, and the Worth Health Organization International Clinical Trials Registry Platform (WHO ICTRP) from database inception to 23rd February 2022. Terms such as “pregabalin”, “gabapentin”, “gabapentinoid” and ”cease”, “taper”, “reduce” and “deprescribe” were used to identify potentially eligible studies. There were no language or publication date restrictions. The full search strategy is outlined in Appendix 2. We then conducted manual screening, searched the reference lists of included studies, as well as backward and forward citation tracking of the included studies using PubMed and Scopus. We also communicated with content experts to identify any missing studies.
