Thirdly, we did not set any arbitrary cut off values.
Such studies should also provide better cut-off values for patients' stratification than the arbitrarily chosen median expression levels in LNs, and enable the ROC curve analysis.
Unlike those studies, the current study used the GFR as a continuous variable and defined the cut-off value with the ROC curve, showing stronger objectivity and accuracy, which demonstrated that even with the presence of better cut-off values, a GFR < 60 mL/minute/1.73 m was still a significant predictor of mortality, independent of which equation was used.
The better cut-off value of the MMSE scores given by the UVAs was 21 (88.8% correctly classified).
Cut off-values used are given in Table 1.
The cut off values proposed by Trang et al better predict fibrosis stages in co infected patients and we applied on only HCV infected patients.
The optimal IEL lymphogram cut off values for active CD diagnosis were: ≥10, ≥15 and ≤9 %, and with better performance characteristics for silent CD: ≥ 11, ≥10 and ≤5 %.
Deficit cut off values for continuous variables by sex and source of cut off.
Before this type of study is available, individual data meta-analysis may also provide better insight into the age-specific best cut-off value in this clinical setting.
Using a cut off value of 8 cells/50,000, antigenemia was found to be the assay that better identified patients at risk of developing CMV disease.
Achievement of PTH and hemoglobin goals was better in that study, however, cut-off values were different from the ones recommended by K/DOQI, making a direct comparison difficult.
