Table 2 Univariate Cox regression analysis of chronic hypersensitivity pneumonitis patients demonstrating mortality according to CALIPER indices (top white), visually derived CT indices (light grey), pulmonary function tests (dark grey), echocardiography, and clinical indices (lower white). ILD = Interstitial lung disease, DA = decreased attenuation, TxBx = traction bronchiectasis, PA = pulmonary artery, Ao = Aorta, PVV = pulmonary vessel volume, FEV₁ = forced expiratory volume in one second, FVC = forced vital capacity, TLC = total lung capacity, DLco = diffusing capacity for carbon monoxide, Kco = Carbon monoxide transfer coefficient, CPI = composite physiologic index, RVSP = right ventricular systolic pressure, NS = not significant
