  1. Data are presented as mean (SD) or n (%) or median (range)
  2. Comorbidities include hypertension, diabetes and coronary heart disease. FEV1% pre, forced expiratory volume in one second as a percentage of predicted value; FVC % pre, forced vital capacity as a percentage of predicted value; MVV % pre, maximal voluntary ventilation as a percentage of predicted value; DLCO, lung diffusion capacity of predicted. In view of small sample size of patients with comorbidities, they are combined into one group for statistical analysis; * 23% (26/113) of the patients with massive hemoptysis underwent emergency surgery without preoperative pulmonary function examination, and 87 cases had pulmonary function examination results
