However, we consistently observed better discriminatory performance of the assay when performed with samples taken from patients three weeks after exposure to the 2009 H1N1 influenza virus.
The level of depression in our sample may not have been so severe as to make this item successfully exhibit discriminatory performance, and it tends to perform better with a larger sample or with a sample with different characteristics, as found in other studies.
To examine the discriminatory performance of donor corneoscleral rim cultures for predicting endophthalmitis after corneal transplantation.
The discriminatory performance of the 6-month prognostic model yielded an AuROC 0.81 (95% CI 0.76 0.86), 0.73 (95% CI 0.69 0.78) and 0.76 (95% CI 0.69 0.83) for the derivation, geographic and temporal external validation cohorts, respectively.
When evaluated using a receiver operating characteristics (ROC) curve, the discriminatory performance of the 6-month prognostic model in the UK derivation sub-cohort yielded an AuROC of 0.81 (95% CI 0.76 0.86) as indicated in Fig. 1a.
In contrast, we obtained an adequate discriminatory performance with a simpler method, using only the peak systolic velocities at a single respiratory cycle, which showed good inter-observer agreement and reproducibility.
It was found that the sheep could identify human faces and while they showed a small inversion-induced decline in discriminatory performance, this was significantly less than seen with sheep faces.
Due to this selection bias, a much higher proportion of nodules in these studies is malignant (~25 %) than in an unselected population (~5 %) and most are papillary carcinomas (~90 %); thus published discriminatory performance data actually refer to this histological type [29, 30, 31, 32, 33, 34, 35].
The value of a DOR ranges from 0 to infinity, with higher values indicating better discriminatory performance or higher accuracy of the test [43] [45].
Weighting the presence of specific susceptible or protective genotypes according to their individual odds ratios (OR from univariate regression or point estimates from multivariate regression) did not significantly improve the discriminatory performance of the raw SNP score (unpublished data).
To detect the most suitable set of miRNAs that achieves the best discriminatory performance, a feature extraction (subset selection) method relying on t-test p-values has been used.
