Data are presented as absolute values (mean ± standard deviation). Statistical analysis between groups was performed with relative changes compared to corresponding preoperative baseline values. For abbreviations, see Table 2. FVC, forced vital capacity. FEV1, 1-second expiratory volume. PEF, peak expiratory flow. MEF25–75, midexpiratory flow (25–75).
