Blinding of the reference test was also poorly reported as was the use of any treatment in between the index test and reference standard.
If the data were however analyzed ignoring the differences between the reference tests, the differences in diagnostic accuracy between T1 and T2 were overestimated (Fig. 2 d– f, Models 4.ii and 5.ii).
The time between the index and the reference test, the index and the comparator test, the comparator and the reference test was not reported in any of the studies.
The second reported no sensitivity or specificity; instead there was correlation between their tool and the reference test (Abuse Risk Inventory, r = 0.69, p = 0.01) but this does not necessarily indicate a valid and specific measure of IPV [ 21].
As the time delay between the PHQ-9 and the reference test varied, we performed an additional analysis to determine the influence of this time delay.
Correlation between the ST sample result and the reference test result was determined by linear regression, and Spearman's rho correlation coefficient.
The test structures were fabricated on the bare MgO substrate (reference sample or 'Ref') and the multilayer (test sample or 'Test') to determine the attenuation and phase constants with and without the film test samples, which were used to compare the propagation characteristics between the reference and test samples.
The underlying preservation statistics are based on permutation tests and their values represent evidence that a module is significantly better preserved between the reference and test networks than a randomly sampled group of genes of the same size.
This location is based on the correspondence features Fr and Ft between the reference and test images.
In this evaluation scheme, 0 means that there is no perceptible difference between the reference and test animations.
In [11], two objective metrics (3DWPM1 and 3DWPM2) derived from two definitions of surface roughness are proposed as the change in roughness between the reference and test meshes.
