22 August 2007	New search has been performed	The sleep data from the Milross trial, which appeared in the graphs removed in the previous update of the review, have now been more appropriately analysed using GIV methodology and are presented in this update. A new search identified seven new references to six studies. One of these references was to an already included study (Holland 2003). Of the remaining six references to five studies, three have not been included as they were not randomised controlled trials in which a form of pressure preset or volume preset NIV versus no NIV was used in people with acute or chronic respiratory failure in CF and they have been added to the excluded studies section (Falk 2006; Fauroux 2004; Greenough 2004). Two studies were included as they fulfilled inclusion criteria (Placidi 2006; Young 2006).
