| Independent variables | Dependent variables | ||
|---|---|---|---|
| VC | FEV1 | IC | |
| B (95% CI) | B (95% CI) | B (95% CI) | |
| Males versus female | −4.90 (−10.4, 0.59)† | — | −19.4 (−25.4, −13.5)∗ |
| Age/10 years | 3.00 (0.53, 5.50)∗ | 3.03 (0.40, 5.70)∗ | — |
| BMI weight (kg)/length m2 | — | −0.78 (−1.42, −0.13)∗ | −0.70 (−1.49, 0.08)† |
| CABG versus valve surgery | — | 5.29 (0.58, 9.99)∗ | — |
| ICU time/4 h | — | −0.34 (−0.66, −0.24)∗ | — |
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, † P = 0.05–0.10, B: regression coefficient, CI: confidence interval.
