  1. Coefficient (B) and 95% confidence intervals (CI) for variables with a statistically significant (p < 0.05) contribution to explain the magnitude of abdominal aortic calcification (AAC), measured by Kauppila Index (KI), in a multivariate linear regression model including all the patients (Model 1) or patients with an estimated eGFR below 30 ml/min (Model 2). The coefficients of determination (r2) for Model 1 and 2 were 0.301 and 0.286, respectively.
