One study, involving 18 participants, reported no significant differences in sputum weight. Lack of protocol data made assessment of risk of bias unclear for the majority of other criteria.įour studies, involving 28 participants, reported a higher amount of expectorated secretions during chest physiotherapy as compared to a control. Blinding of participants, caregivers or clinicians in airway clearance studies is impossible therefore this was not considered as a high risk of bias in the included studies. This enormous heterogeneity in the treatment interventions prevented any meta‐analyses from being performed. Of the eight studies, six were single‐treatment studies and in two, the treatment intervention was performed over two consecutive days (once daily in one, twice daily in the other). One included study looked at autogenic drainage, six considered conventional chest physiotherapy, three considered oscillating positive expiratory pressure, seven considered positive expiratory pressure and one considered high pressure positive expiratory pressure. There were differences between studies in the way that interventions were delivered, with several of the intervention groups combining more than one treatment modality. ![]() The searches identified 157 studies, of which eight cross‐over studies (data from 96 participants) met the inclusion criteria. ![]()
