To determine the effect of stimulus size on sensitivity of patients with retinitis pigmentosa (RP) as measured by automated static perimetry.
Cohen d analyses revealed a small effect size for all variables (effect size for sensitivity of d=0.24 at six months and d=0.26 at 12 months; d=0.26 and d=0.24 for intrusiveness).
In the test on the independent dataset, DPI2 showed the best result with a window of size 31 (sensitivity of 67.61%, specificity of 74.27%, accuracy of 71.37%, PPV of 66.95%, NPV of 74.84% and MCC of 0.418).
DPI1 showed the best result with a window of size 23 (sensitivity of 74.01%, specificity of 72.92%, accuracy of 73.42%, PPV of 70.16%, NPV of 76.53% and MCC of 0.468).
This may have been due to the sample size and/or lack of sensitivity with respect to the proxy variables, 'highest level of education' and 'parent/ caregiver occupation'.
First, data were generated using a simulation in which the 'true' drug efficacy (TDE) was evaluated by the FECRT under varying scenarios of sample size, analytic sensitivity of the diagnostic technique, and level of both intensity and aggregation of egg excretion.
He said the new series would be "largely technologically led in that we can do things that we couldn't before, in terms of the size and sensitivity of cameras, drones, all that sort of stuff.
"They seem to be knowledgeable and respectful of the size and sensitivity of the job.
The influence of size of platform on sensitivity and the load bearing capacity are discussed in the light of capabilities of available sensing elements.
The extent to which this is true and the possible size of age-related sensitivity differences has not been well studied.
