  1. 6MWT, 6-min walking test; CG, control group; FEV1.0, forced expiratory volume in the first second; FVC, forced vital capacity; PEF, peak expiratory flow rate; Preop, preoperative; Postop, postoperative; SG, studied group; VC, vital capacity
  2. All variables were compared by t-tests. p ≤ 0.05 was regarded as statistically significant
