Pulmonary function data are presented as percentages of predicted values except forced expiratory volume in one second (FEV₁)/forced vital capacity (FVC), which is a percentage
T_L,CO: carbon monoxide transfer factor
TLC: total lung capacity
VHD: valvular heart disease
DM: diabetes mellitus
TB: tuberculosis
