^*Six patients did not have radiologic data available for review.

^**Pearson χ² test and one-way analysis of variance were used to compare categorical and continuous variables, respectively

SD=standard deviation; FEV₁=forced expiratory volume in one second; FVC=forced vital capacity; RV=residual volume; DL_CO =carbon monoxide diffusion capacity
