Data are shown as means±SDs. Brackets indicate percentages.
p Values were calculated by comparing patients with HP with healthy volunteers and patients with IPF by using Tukey's test.
DLco, diffusing capacity of the lungs for carbon monoxide; FEV1, forced expiratory volume in 1 s; ND, not determined; NS, no statistical significance; TLC, total lung capacity; VC, vital capacity.
