Cardiopulmonary exercise test (CPET) testing is the gold standard
exercise test in CF. Elevated breathing reserve index at anaerobic
threshold (BRIAT) is a prognostic indicator of mortality in CF adults
awaiting transplant, but no data on BRIAT in the paediatric CF
population are reported. The aim of this study was to investigate the
relationship between BRIAT and morbidity (death or transplant) in
children with CF.
