ROC curve analysis for the optimal cut-off point of MLR.Liang, WangWen, LongPengFei, LiYongBin, LinYing, Liang
For plotting the ROC curve with labeled points, the ROCPLOT macro provides these capabilities: The macro enables you to label points with any number of statistics in addition to variable values. Any given cutpoint can correspond to many observations in the data. When using variable levels to la...
In addition, the achieved performance of the dichotomized biomarker classification associated to the estimated cut-point can be represented through a confidence interval of the point on the ROC curve. Keywords: Optimal cut-point, Censored failure time outcome, Youden index, Concordance probab...
Optimal Centiloid cut-offs were sought that maximize the agreement between PET and dichotomous determinations based on CSF levels of Aβ42, tTau, pTau, and their ratios, using pre-established reference cut-off values. To this end, a receiver operating characteristic analysis (ROC) was conducted...

The optimal cut point was defined as the point on the ROC curve from where the distance to the point where both sensitivity and specificity were one was minimal.Results The correlation coefficients of HbA1c with other MS-related components and the area under ROC curve (AUC) of HbA1c for ...
optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off val...
Therefore, we considered obtaining the best CYFRA 21-1 cutoff point in our population using the Youden test. The Youden test obtained with the ROC curve (Figure 1) showed 3.15 ng/mL to be the optimal cutoff (71.8% Youden test) acquiring an AUC of 0.915 (95% CI, 0.863–0.966). This ...
3.5.3. Figure 1 Percentage body fat cut-off by at least one of CRF, separately for men and women. Optimal cut-off values were determined as a specific point on the curve whereupon Youden index (defined as sensitivity + specificity-1) was at the maximum. The area under the curve (AUC)...
Receiver operating characteristic (ROC) curve was used to find out the best cut-off point of viral load before 22 weeks to predict the high viral load (6, 7, 8 log10 IU/mL) at 28-30 weeks of gestation. The best cut-off point was defined as the point with maximum Youden's index....
