We also planned to report cut off levels, specificities, positive predictive values, negative predictive values, positive likelihood ratios and negative likelihood ratios with sensitivities of approximately 80%.
In addition to those reporting cut-off values according to time course interval listed in Table 4, the following four studies investigated the clinical usefulness in predicting neurological outcome after CPR not in accordance with time course interval.
Though, unlike the typically higher prevalence rates of overall mental health problems in older children and adolescents, our results based on the parent reported cut-offs suggest a small decrease of the reported common mental health problems in the older age group.
However, reported cut-off values depend on the device used for the measure.
The broad clinical use of 18F-FET PET requires comparable quantitative parameters, but as yet, the reported cut-off values of different parameters like TBRmean, TBRmax, TTP, slope and Tvol for tumour grading or differentiation of recurrent tumour from treatment related changes appear to vary among different centres.
For the differentiation of recurrent tumours from treatment-related changes which is a frequent clinical question, the reported cut-off value for TBRmax was 2.0 in centre A and 2.3 in centre B which might also reflect the difference in data processing in the two centres [12, 25].
A commonly reported cut-off value is.06 (Hu and Bentler 1999).
Repeat testing was also described in two European studies, but reported cut-off values differed.
Additionally, the reported cut-off level for CRP was different in each study.
For serum-based studies, this took into consideration a reported cut-off as determined by the authors of each study.
Therefore, similar results were obtained when we employed tertile cut-offs to define increased EBV DNA levels compared with previously reported cut-offs.
