Ory power among predictor models. In assessing cardiovascular events, the Combined model was significantly better than GFR (difference between AUC: 0.150, 95 CI 0.004-0.260, p = 0.008) and showed a trend for a higher discriminatory power than Framingham (difference between AUC: 0.184, p = 0.052), age (difference between AUC: 0.135, p = 0.078 and the Clinical model (difference between AUC: 0.065, p
Al data. Continuous variables of time were also described with median, minimum and maximum value. The Kolmogorov-Smirnov test was used to test the normal distribution of continuous variables. The Chisquare test, Student's t-test and non-parametric equivalent tests were used when appropriate. Regression estimation techniques were applied to replace missing values whenever the number of missing valu
Months (range 18 - 68) was performed. During this period, 10 cardiovascular events (11.8 ) were reported: one unstable angina (1.2 ), seven strokes (8.2 ) and two cardiovascular deaths (2.4 ) ?Table 5. No events were observed in patients with zero CS (0 vs. 19.2 , p = 0.007) or without atherosclerotic plaques (0 vs. 17.5 , p = 0.018), both presenting a negative predictive value of 100 . Seven ev

Utoff point the Youden index, which is the point on the ROC curve where optimal sensitivity and specificity are achieved. Predictor models were created trough multivariate analysis (binary logistic regression with the method Enter) using events predictors (as continuous variables whenever possible): Clinical model, comprising GFR, age and Framingham evaluated before CT; CT model, comprising CS, ob
