New search has been performed

A search of the Group's Cystic Fibrosis Trials Register identified three new references to two new studies (Grzincich 2008; Kraemer 1996). We included the Grzincich study as this compared HFCWO with PEP (Grzincich 2008). We excluded the two references to the Kraemer study as they did not compare oscillation with another form of physiotherapy treatment (Kraemer 1996).

We identified the full paper to a previously identified abstract and this now supercedes all previous references and has been included in this review (Osman 2010). We also identified the full paper to another previously included study (Modi 2006a) and this is listed as 'Awaiting classification' until the next update when we will include any new data.

Three studies which were listed as 'Awaiting classification' have now been translated and assessed for eligibility.These studies were included in this updated review (Orlik 2000a; Orlik 2000b; Orlik 2001).
