ROC curve for subclinical atheromatosis (SAT) detection in HIV participants without previous cardiovascular disease. Receiver operating characteristics curve evaluating the accuracy SAT detection in participants with HIV without previous CVD. AUC: area under the curve (95% confidence interval); X: mean; SD: standard deviation. The probability of presenting atheromatous plaque was calculated using the following formula: \(\mathrm{P }(\mathrm{Plaque}) =\frac{1}{{1+e}^{-(3.963-0.077*Age-0.092*CD4/CD8\left(if<0.7\right)-0.933*(if active smoker)}}\) where P: the probability of presenting atheromatous plaque; e: exponential constant; Age: age in years; CD4/CD8: 1 if CD4/CD8 < 0.7; Active smoker: 1 if an active smoker
