Figure 3

Validation of the logistic model identifying factors independently associated with severe abdominal aortic calcification. ROC curve depicting the high sensitivity of the logistic regression analysis of factors independently associated with severe abdominal aortic calcification (KI < 5) vs. no calcification (KI = 0) including all patients. The ROC curve includes male gender, age, CKD stage, the presence of carotid plaques, and the log2 (FEP/FGF23). The ratio FEP/FGF23 was introduced as a binary variable with a cutoff point of 1/3.9.
