In the DISCOVER-FLOW (Diagnosis of Ischemia-Causing Stenoses Obtained Via Noninvasive Fractional Flow Reserve) trial [ 86], FFRCT was performed on 159 vessels in 103 patients with suspected or known CAD undergoing CCTA and invasive coronary angiography.
As with the analysis of psychophysical data, COH is the coherence of the motion stimulus on that trial, in fractional units of the maximum coherence employed and signed to signify the direction of motion.
This study is a fractional factorial, randomised control trial of the diffusion of a Facebook application for smoking cessation.
CORONIS is a multicentre, fractional, factorial randomised controlled trial and will be conducted in centres in Argentina, Ghana, India, Kenya, Pakistan and Sudan.
Finally, for each loaded trial, the fractional change in metabolic rate was determined as the product of loaded net rate and mean unloaded net rate.
If the number of antibiotics increases to 13, a full factorial design will require 1,594,323 (313) trials while the fractional factorial design can reduce the number of trial to 27 only.
The design contains a total of 54 experimental trials with the first 32 organized in a fractional factorial design and experimental trials from 33 to 40 and 51 to 54 involving the replications of the central points.
The CORONIS Trial is a fractional factorial design, and, therefore, each participant was allocated only three out of the five possible interventions.
Figure 2b shows the fractional factorial design of 9 trials out of the 27 tests required in a full factorial design.
In order to tracking the reference trajectory associated with nonlinear fractional differential systems with randomly varying trial lengths, we design a new type iterative learning control of the output equation with nonlinear input involving an integral term.
The MRC funded CORONIS Trial is a 2×2×2×2×2 fractional, factorial trial of different surgical techniques at caesarean section.
