PPCs: postoperative pulmonary complications, OR: Odds ratio, BMI: Body mass index, CK-MB: creatine kinase MB. Odds ratios show the relative incremental risk of each complication when the predictive factor is present. Logistic regression provides 95% confidence intervals as an estimation of relative risk in the general population
