Peak Oxygen Uptake and Mortality in Cystic Fibrosis: Systematic Review and Meta-Analysis.
Aerobic fitness, as measured by peak oxygen uptake (V̇O2 peak), correlates with survival in children and adults with cystic fibrosis (CF). We sought to evaluate the effects of V̇O2 peak on mortality rates in subjects with CF. ⋯ Low levels of peak oxygen uptake are associated with an increase of 4.9 in the risk of mortality in subjects with CF. This indicates that V̇O2 could be an important follow-up variable to measure, in addition to FEV1.
