In postmenopausal women, an endometrial lining measuring <5 mm is considered an accurate cut-off in excluding endometrial disease.
The cut-off score of > 5 has been found to be an accurate cut-off score to distinguish between patients with primary insomnia and those without insomnia [ 18].
Consequently they may not be correct when evaluating the response to treatment and greater efforts to find more accurate cut-off points for treatment efficacy should be made.
However, only few studies have investigated which is the most accurate cut-off value that could represent methylated or unmethylated status.
5 In another study, Eid and Pottala used a receiver operating curve to determine that an HbA1c ≥6.3% provided the most accurate cut-off measurement for diagnosing diabetes within a chronic disease management system, particularly within high-risk populations.
The most accurate cut-off value capable of discriminating between healthy women and cancer patients, in the absence of internationally accepted cut-off values for serum bFGF and VEGF concentrations, was identified using a receiver operating characteristic (ROC) curve analysis.
Because of the lack of a reference signal, the non-MRSA252 spots could not be normalised in the ratio dependent way or by auto-scale normalisation since the latter will reduce differences in the intensities, which compromises calculation of an accurate cut-off for gene presence or divergence.
In those meta-analyses, accuracy data from non-standard cut-offs have been included when primary studies only report optimally accurate cut-offs, but do not report less optimal accuracy results from standard cut-offs.
However, there is no consensus regarding the general protocols for the measurements of NC [ 16] and WC [ 9], and there are no accurate cut-offs values for children and adolescents to define high NC.
We analysed the observed mortality vs predicted mortality ratio (OM/PM), sensitivity, specificity and percentage of accurate prediction for a cut off point of 50% of probability of death.
