Figure. Receiver operating characteristic (ROC) curves using Tool for Assessing Glucose ImpairmenT for Adolescents (TAG-IT-A) and body mass index (BMI) alone with NHANES III data to predict glucose levels ≥100 mg/dL among adolescents. The TAG-IT-A model is a tool developed for use in the community to assess risk of glucose impairment in adolescents. The area under the curve for TAG-IT-A is 0.61 (P < .001) and for BMI only is 0.55 (P = .10). Abbreviations: ROC, receiver operating characteristic; TAG-IT-A, Tool for Assessing Glucose ImpairmenT among Adolescents; BMI, body mass index; NHANES III, National Health and Nutrition Examination Survey, 1999-1994.
