Table 1 Patient age, gender and mean and standard deviations of pulmonary function indices, CALIPER and visually scored CT parameters, and echocardiography data in patients with chronic hypersensitivity pneumonitis. Data represent mean values with standard deviations. CT computed tomography, FEV1 forced expiratory volume in one second, FVC forced vital capacity, DLco diffusing capacity for carbon monoxide, Kco carbon monoxide transfer coefficient, TLC total lung capacity, CPI composite physiological index, ILD interstitial lung disease, RVSP right ventricular systolic pressure, TxBx = traction bronchiectasis. Baseline variables in patients with hypersensitivity pneumonitis
