Associations between emphysema at enrollment and clinical outcomes.^aAdjustment variables included in the models were as follows (all at enrollment): age, BMI, FVC % predicted, DLco % predicted, oxygen use at rest, and history of coronary artery disease or heart failure for time to death. Age, BMI, FEV₁ % predicted, FVC % predicted, DLco % predicted, oxygen use at rest, oxygen use with activity, and prior diagnosis of IPF (before referral to enrolling center) for time to lung transplant. BMI, FEV₁ % predicted, and oxygen at rest for time to hospitalization. Age, BMI, FEV₁ % predicted, FVC % predicted, DLco % predicted, oxygen use at rest, oxygen use with activity, history of coronary artery disease or heart failure, and prior diagnosis of IPF (before referral to enrolling center) for time to death or lung transplant and for time to death, lung transplant or hospitalization
