We considered all randomised controlled trials (RCTs) assessing
the efficacy of chest physiotherapy for adult participants with any
type of pneumonia. We included trials which also included other
basic respiratory diseases, once pneumoniawas diagnosed;we analysed
such trials separately.We excluded trials in which physiotherapy
was administered for the prevention of pneumonia, as pneumonia
could occur in many conditions, such as trauma, cerebral
vessels disease and postoperative conditions. We included both
published and unpublished trials.
