From: Longitudinal changes in pulmonary function and patient-reported outcomes after lung cancer surgery
Change in pulmonary function and patient-reported outcomes by type of surgery and postoperative time. (A) FVC (mL), (B) FVC (percent of the predicted value), (C) FEV1(mL), (D) FEV1 (percent of the predicted value), (E) mMRC dyspnea scale, (F) CAT according to type of surgery and postoperative time CAT chronic obstructive pulmonary disease assessment test, FEV1 forced expiratory volume in 1 s; FVC forced expiratory vital capacity, mMRC dyspnea scale modified Medical Research Council dyspnea scale. *P for interaction (P < 0.01) between type of surgery (reference: lobectomy) and time after adjustment for age, sex, smoking status, obesity, stage, cell type, type of surgery, video-assisted thoracic surgery, postoperative pulmonary complications, and adjuvant treatment
