The overall diagnostic performance of overlay images was found to be good in the ROC analysis
(AUC 0.847; P < 0.001).
The sensitivities and specificities for different values of PPV were plotted on a curve and urine output within 120 seconds of revascularization of the graft used as the desired value for ROC analysis
Table-III: PTX-3 levels of the malignant and benign patients with ROC analysis
results performed for estimation strength of the malignant cases.
Based on ROC analysis
, the best statistical cut-off value was calculated.
Basic principles of ROC analysis
. Semin Nucl Med 1978; 8: 283-98.
The diagnostic accuracy of serum Tg and Tg/TSH was evaluated using ROC analysis
. The ROC curve is illustrated in Figure 2.
showed that the AUC values for podocalyxin, nephrin, NGAL, and KIM-1 were >0.7.
The relation between WHtR, four skinfolds (triceps, subscapular, supraspinale and calf), sum of four skinfolds, body fat% and overweight/obesity as defined by the IOTF was investigated with ROC analysis
. The discriminating power was expressed as area under the curve (AUC).
showed that all curves for anthropometric parameters (i.e., BMI, BMI z-score, WC, WHtR) have comparable and excellent discriminatory capability (AUC>0.800) towards inflammation status level (low vs.
The ROC analysis
was applied to determine the cut-off values, which are the critical cut-off points for the minimum monocyte, maximum RDW values, and APACHE II score measurements that are thought to be susceptible to mortality.
They reported the admission NLR cut-off value as 10.6, day 1 NLR cut-off value as 8.1, and day 2 NLR cut-off value as 4.8 in their ROC analysis
to predict patients with mild and severe AP.
Based on the ROC analysis
, the increasing trend of NT-pro BNP levels during ICU stay was predictive of mortality with area under curve (AUC) of 0.84 (p<0.0001, 95% CI: 0.75-0.93) at cut-off value > 5543 (sensitivity: 80%; specificity: 79%, PPV: 0.53, and NPV: 0.93) (Figure 2).
