The multivariable logistic regression model selected seven independent predictors of PPCs: age ≥70 years (odds ratio (OR) 2.03; 95% confidence interval (CI) 1.37–3.00; p<0.001), current smoker within 2 months (OR 1.62; 95% CI 1.03–2.54; p = 0.036), ASA class ≥2 (OR 1.59; 95% CI 1.01–2.52; p = 0.046), airflow limitation (OR 1.75; 95% CI 1.18–2.58; p = 0.005), serum albumin <4.0 g/dL (OR 1.49; 95% CI 1.00–2.21; p = 0.049), emergency surgery (OR 2.16; 95% CI 1.00–4.65; p = 0.050), and cardiac/aortic aneurysm repair/abdominal open surgery (OR 7.02; 95% CI 4.04–12.19; p<0.001). Here, ALB is linked to aortic aneurysm.
