Figure 1 ROC Curves for Adolescent Lipid Measures Predicting Adulthood IMT  90th Percentile or Carotid Plaque
Ages 12 to 18 years, n = 472. The diagonal line indicates a test with an area under the receiver operating characteristics curve of 0.5. In addition to lipid measures, the models included those risk factors significantly associated with intima-media thickness in multivariate model (blood pressure, smoking). The values for continuous variables were age- and gender-specific Z scores. ApoA-I = apolipoprotein A-I; ApoB = apolipoprotein B; HDL = high-density lipoprotein (cholesterol); IMT = intima-media thickness; LDL = low-density lipoprotein (cholesterol); ROC = receiver-operating characteristic.
