Comparison of the emphysema index (EI) and the predictive percentage value of the pulmonary function test using a receiver operating characteristic curve analysis. The area under the curve was for EI, for forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC), for FEV1, and for the diffusion lung capacity to carbon monoxide (DLCO).
