*‘Level of evidence’ ranges from evidence obtained from a systematic review of all relevant randomised controlled trials (level I) to evidence obtained from case series, either post-test or pre-test and post-test (level IV).25 †The Consolidated Standards of Reporting Trials (Consort) statement is a checklist to improve the quality of reporting of randomised controlled trials.26 Where data are missing, rows do total 100%. | |||||
