AAA, abdominal aortic aneurysm; BNP, type-B natriuretic peptide; Cr, creatinine; eGFR, estimated glomerular filtration rate; Hb, hemoglobin; Plt, platelet; PT, prothrombin time; WBC, white blood cell. Continuous variables are presented as the mean ± standard deviation if normally distributed or the median (interquartile range) if not normally distributed. Categorical variables are presented as the number of patients (%). The bold values represent a statistical difference between the two groups.
