In the following, by referring to the result in [17, 18], we give a method to determine the threshold, by which the threshold value will be derived from the constant false alarm rate.
Firstly, we should set a predefined threshold Tth for checking the presence of nonzero second-order CC at interest delay, and the determination of the threshold value will be derived in Section 4.3.
When setting this value, an integer-based velocity value will be derived and stored.
Utility values will be derived from the EQ-5D and from the SF-36 using the algorithm provided by the SF-6D.
Estimates of population values will be derived by standard methods for analysing a multistage cluster sample.
Utility values will be derived using Brazier's algorithm [ 75, 76].
At baseline (the pre-operative assessment) and each follow-up point, simple 10 cm visual analogue scales (VAS) will be used to record least and usual back and leg pain, from which average values will be derived [ 58].
Can you talk a bit about the progress made there, the role that IT plays in that, and where you see the value that will be derived for the company and for the company's customers, ultimately, through the Internet of Things?
Additionally, a cost-utility analysis will be performed to enable comparisons to be drawn with other areas of health care; utility will be measured using QALY values, which will be derived separately from (i) the EuroQoL EQ5D, and (ii) the SF-12 SF-6D.
At the end, reliable estimators of the diagnostic accuracy (sensitivity, specificity, predictive value, limits of the test) will be derived from the trial.
19 Data (eg, NHS resource use and costs, service model efficacy, event and risk probabilities and utility values) for the economic model will be derived from the literature review, from the DCE interviews, from retrospective retrieval of hospital and general practitioner records and from clinical experts.
