6 January 2016	New citation required but conclusions have not changed	A new author (Dr R Lord) has joined the review team. No additional studies have been included in the review and our conclusions remain the same.
6 January 2016	New search has been performed	A search of the Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Register identified 21 references potentially eligible for inclusion in the review. Of these we retrieved a total of seven papers, all for the same study, which had previously been listed as 'Awaiting classification' (Tullis 2014). This was then excluded as it was not a therapy for an acute exacerbation.
