In October 2020, searches were completed of the Cochrane Central Register of Controlled Trials (CENTRAL), PEDro (Physiotherapy Evidence Database), PubMed, MEDLINE, and Science Direct databases without restrictions on year, publication status, or language. Unpublished work was identified by searching Pediatric Pulmonology and the Journal of Cystic Fibrosis for the abstracts of two major CF conferences, the European Cystic Fibrosis Conference, and the North American Cystic Fibrosis Conference. Separate searches of clinicaltrials.gov, International Standard Randomised Controlled Trial Number (ISRCTN) registry, and the World Health Organisation’s International Clinical Trials Registration Platform (WHO ICTRP) databases were performed.
