All covariates were entered into the adjusted model. Associations are reported for the outcome, namely the percentage change in the maximum orthogonal abdominal aortic aneurysm diameter (AAAd; measured by plain multislice computed tomography) at the 24-month follow-up vs. baseline diameter. The mean value SBP at baseline was set as the cut-off value (129 mmHg; minimum 94 mmHg, maximum 143 mmHg). ARB, angiotensin receptor blocker; CCB, calcium channel blocker; CI, confidence interval; OR, odds ratio. Other abbreviations as in Table 1.
