  1. Model 1 adjusted for sex, age and relevant confounders, including BMI, FFMi, FEV1/FVC, TLCO, RV, TLC, diastolic blood pressure, PaO2, long-term oxygen therapy, smoking status, smoking pack-years, blood glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, cardiovascular medication; Model 2 adjusted for all variables in model 1 plus fellow vessel diameter (i.e. CRVE in model for CRAE or vice versa).
