Compared with the control group, participants in the Acapella plus ACBT group had significantly improved FEV1% of predicted at the 1-week (difference = 13.35; 95% CI, 9.83–16.87; Among the remaining lung function parameters, between-group differences in the FVC% of predicted followed a similar pattern to FEV1% of predicted; FVC% of predicted significantly improved in the Acapella plus ACBT (1-week follow-up: difference = 14.00, 95% CI, 10.39–17.6; Another secondary outcome in this study was the incidence of PPCs in patients with lung cancer, including pulmonary infection, hypoxemia, and atelectasis. In total, 54 (14.88%) of the 363 participants were diagnosed with PPCs, including 28 (23.14%) of 121 in the control group, 16 (13.01%) of 123 in the Acapella plus ACBT group, and 10 (8.40%) of the 119 in the EDP plus ACBT group (Table
