ROC curve analysis for the optimal cut-off point of MLR.Liang, WangWen, LongPengFei, LiYongBin, LinYing, Liang
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 ...
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...
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...
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 ...
between the time elapsed since endoscopic resection and a combination of operative time and the amount of intraoperative blood loss. The greatest difference and the change of the slope of the graph was around day 29 (the cut-off point), and no significant difference was evident from after day...
In our population, based on the ROC curve, the CA125 value of 75 UI/ml is the best cut-off to identify the patient candidates that are optimal cytoreduction agents with a sensitivity of 81.3 % and a specificity of 85.7 % (PPV = 86.7 % and NPV = 80 %). For CA125, the ...
(1 - specificity): points on a ROC plot along this line represent a cut point at which no reliable discrimination has been found. B. Plot of guess or incorrect choice as a function of Q value for the compressed image. The percentage of responses representing an incorrect choice or a ...

According to the ROC curve model, the cut-off point of grip strength was calculated, when mobility limitation was selected as the target variables. Results: According to the results of ROC curve, In man, grip strength is lower than 32.45 kg, the strength is weaker, Sensitivity is 79.7% ...
