According to treatment need, malocclusions were divided into two groups (23): no treatment need [DAI [less than or equal to] 25 (grade 1)] and treatment need [DAI > 25 (grades 2-4)] to compare with PAR scores and find the cut-off points for the PAR index with regard to Angle classification of malocclusions.
Therefore, in this study, it was aimed to calculate the cut-off points for PAR index in accordance to Angle classification by DAI.
In contrast, the optimal cut-off points for IR surrogates were very similar in almost all the studied definitions (Table 3).
Finally, Kappa coefficients (K) and percentage of agreement between the average cut-off points for IR surrogates and different definitions of MS are shown in table 4.
Metabolic syndrome was defined as according to the criteria suggested by International Diabetes Federation (IDF).13 This includes central obesity measured by ethnicity specific cut-off points of WC (males:90 cm, females:80cm) plus any two of the following four criteria: High blood pressure (systolic 130mmHg or diastolic 85mmHg) or taking medicines for previously diagnosed hypertension; Triglycerides 150mg/dL or taking specific treatment for it; Decreased high-density lipoprotein(HDL) cholesterol (males: < 40mg/dL, females: 100 mg/dL, an oral glucose tolerance test should be done, however, it is not needed to diagnose metabolic syndrome.)
Receiver operating characteristic (ROC) curves were constructed and cut-off points were determined to evaluate the accuracy of NC as a predictor of MS.
 published their WC cut-off points
based on ROC curves using visceral fat area ([less than or equal to] 100 [cm.sup.2]) as the independent variable, with resulting cut-off values of 94 cm for men (89.9% sensitivity and 80.2% specificity) and 90-92 cm for women (78.9%-72.9% sensitivity and 676%-74.5% specificity).
Table 4 shows the areas under the ROC curves (AUC), with 95% confidence intervals, for the selected anthropometric indices, with cut-off points
for sensitivity, specificity, balanced accuracy, PPV, and PNV for a MS diagnosis.
Next, sensitivity and specificity were calculated, as well as the cut-off points
for the patterns of physical activity in different settings (work, transportation, domestic activity and leisure activity) and total physical activity total for the absence of frailty.
The optimal cut-off points
, as determined by the ROC curve, are indicated by an arrow in the upper-left-hand corner of the figure; 14 for the Braden scale, 21 for the Song and Choi scale and 28 for the Cubbin and Jackson scale.
Recognising the need to address this pressing issue to define obesity among Asians, WHO convened an expert consultation in July 2002, where Asian and international experts deliberated whether population-specific BMI cut-off points
for overweight and obesity are necessary.
Sensitivity and specificity values for the detection of patients with DSM IIIR diagnoses of delirium and dementia, using the most discriminating cut-off points
of the AMT and IQCODE scores, are shown in Tables 2 and 3.
