  • a The optimal diagnostic threshold for nonfasting triglycerides was determined by evaluating the maximal area under the ROC curve (ie, c-statistic) (40) for univariable logistic regression models with a composite 8-year CVD event as a dependent variable and the dichotomized level of nonfasting triglycerides as an independent predictor. The Youden index is proportional to the c-statistic and defined as sensitivity + specificity − 1.
