A Ppl,max \<30 cmH2O was associated with a significantly greater mortality, Ppl,max being correlated with survival (r=0.79, p\<0.05). At t6, fR, fR/VT, P0.1/Ppl,max, were significantly increased in comparison to to, while FVC \% pred, vital capacity (VC) \% pred, FEV1 \% pred, VT and Ppl,max were significantly reduced. These results suggest a progressive deterioration in breathing pattern and in respiratory muscle strength with progression of disease.}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/10/7/1614}, eprint = {//www.qdcxjkg.com/content/10/7/1614.full.pdf}, journal = {European Respiratory Journal} }
