SR: standard residuals (the deviation from predicted values (recorded−predicted)/residual standard deviation), FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; DLCO: diffusing capacity of the lung for carbon monoxide; KCO: transfer coefficient of the lungs for carbon monoxide; TLC: total lung capacity; RV: residual volume.
