Logistic regression analyse were performed to explore the association between ECW/BCM with CAC. Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of ECW/BCM for CAC.</p>Results<p>A total of 197 PD patients were recruited and the prevalence of CAC was 53.81%. Patients with a higher ECW/BCM ratio had a higher prevalence of CAC and CACS level.

The multivariate logistic regression identified ECW/BCM as an independent risk factor for CAC [per 0.1 increase of ECW/BCM, odds ratio 1.350, 95% confidence interval (CI) 1.089–1.674, p = 0.006]. The area under the receiver operating characteristic curve (AUC) for predicting CAC further increased to 0.869 (95%CI 0.818–0.920) after ECW/BCM was added to conventional factors.</p>Conclusion<p>ECW/BCM was independently associated with the presence of CAC in the early stages of PD.</p>
