VC: vital capacity, FEV1: forced expiratory volume in 1 second, IC: inspiratory capacity, BMI: body mass index, type of surgery (CABG: coronary artery bypass grafting, valve: aorta, mitralis, or tricuspidalis valve surgery), ICU: intensive care unit. ∗ P < 0.05, B: regression coefficient, CI: confidence interval, R 2: adjusted R square.
