In our study, 11 seconds was selected as the threshold value for the TUG test based on receiver operator characteristics (ROC) analysis.
We evaluated whether lowering the interferon-γ cutoff would improve concordance between tests since the current cutoff values are based on receiver operator characteristics in immunocompetent individuals and it is known that HIV-infected patients have impaired interferon responses [ 21].
On receiver operator characteristics analysis, GLS-avg had excellent discriminatory ability to distinguish HCM from H-LVH area under curve (AUC) (0.893, p<0.001) or AT-LVH AUC (0.920, p<0.001).
Two measures of degree of explanation were provided by the SAS logistic procedure, one based on concordance between observed and model computed results, the other based on the receiver operator characteristics (ROC) method.
The results of the TUG test were categorized using a cut-off value of 11 seconds, based on a receiver operator characteristics (ROC) analysis.
The sensitivity and specificity of screening at different risk cut-offs are based on the receiver operator characteristics curve data from AML (Algemeen Medisch Laboratorium bvba), a large laboratory covering 40% of the first and second trimester screening for Down syndrome in Flanders.
The quality of the colonoscopy depends on bowel preparation and operator characteristics [ 51].
The focus on power, FDR and rank have lead many investigators to rely on receiver operator characteristic (ROC) curves [ 8, 10, 14, 15] and FDR plots [ 4, 8] when comparing methods for detecting differentially expressed genes.
Based on receiver operator characteristic (ROC) curve analysis, a cutoff value was identified for prediction of response to treatment (ACR pedi50 or higher).
Based on this large data set with known truth, the authors have performed a comprehensive comparison of segmentation methods for array-CGH data based on receiver operator characteristic (ROC) curves.
