Abbreviations: TAAA: thoracoabdominal aortic aneurysm; CAD: coronary heart disease; DBP: diastolic blood pressure; SBP: systolic blood pressure; BMI: body mass index; eGFR: estimated glomerular filtration rate; HDL: high-density lipoprotein cholesterol; LDL: low-density lipoprotein cholesterol. For the continuous variables, the P value was calculated using the Mann–Whitney test. For the count variable, if there is a theoretical number < 10, the P value was calculated using the Fisher exact probability test. Otherwise, the Chi-squared test was applied.
