The parameters indicating pulmonary functions were assessed using noninvasive pulmonary functionality test system. Data were expressed as median (IQR) and analyzed with Wilcoxon signed-rank test. < 0.05 and < 0.01, when compared with control group; ^▲P < 0.05 and ^▲▲P < 0.01, when compared with CDSCOPD group; ^◆P < 0.05 and ^◆◆P < 0.01, when compared with COPD group; ^◇P < 0.05 and ^◇◇P < 0.01, when compared with the spontaneous recovery group.
