Data are presented as mean value ± SD. *, these marked values of postoperative and post-rehabilitation parameters are better than its preoperative (start-value) was, so at these variables the preoperative and postoperative rehabilitations were able to compensate the functional-depleting effect of the operation. FEV1, force expiratory volume in the first second; FVC, forced expiratory volume; 6MWD, 6-minute walking distance; mMRC, modified Medical Research Council dyspnoea scale; CAT, COPD assessment test; COPD, chronic obstructive pulmonary.
