The authors are indebted to Drs Laura Franzini and Diego Ardigò from the Department of Internal Medicine and Biomedical Sciences, University of Parma, for collecting reliability data.
Based on the information collected, two reliability indexes will be computed and compared, one with data collected from design documentation and literature and the other with data collected from testing, emphasizing the importance of testing and the advantages of Bayesian inference procedures.
Also, we did not collect test-retest reliability data, since acceptable to good reliability data are available for children of the age 5 10 years considered in this study [ 42].
Given their limitations, investigators should routinely collect data about reliability and validity of those measures.
The first 50 participants were invited to return for a second session within 6 8 days to collect test-retest reliability data.
In order to collect test-retest reliability data and to test for changes associated with the intervention in the exploratory RCT, the ANT and CANTAB data were collected on three occasions: 3 weeks before to the intervention; just before the intervention (week 0, just before the intervention began) and following the 10 week intervention or control conditions (end of week 10).
Likewise, the model should provide interpretable results that facilitate explanation of the prognosis, the data required for the model must be relevant and simple to collect with high reliability, and physicians must be able to apply the modeling method correctly without violating the fundamental assumptions of the model.
34 Until an accepted standardized assay is available, clinicians should utilize an assay with demonstrated reliability, collect and process samples appropriately and adjust to appropriate age and gender-matched reference norms, 28 which should be requested from each laboratory whenever possible.
Briefly, we identified key areas within each process in which to collect data relating to reliability.
