  • Hazard ratios reflect the relative risk of death associated with the given variable (or, for continuous variables, a one-unit increase in the variable). FVC: forced vital capacity; DL,CO: diffusing capacity of the lung for carbon monoxide; UIP: usual interstitial pneumonia; % pred: percentage of the predicted value. #: on high-resolution computed tomography.
