Characterizing the diagnostic sensitivity and specificity of pain biomarkers in cattle using receiver operating characteristic curves

Journal of Dairy Science, 2022
: Biomarkers are used to assess pain and analgesic drug efficacy in livestock. However, often the diagnostic sensitivity and specificity of these biomarkers for different painful conditions over time have not been described.

Clostridioides difficile Toxin B PCR Cycle Threshold as a Predictor of Toxin Testing in Stool Specimens from Hospitalized Adults

Antibiotics, 2022
Rapid, accurate detection of Clostridioides difficile toxin may potentially be predicted by toxin B PCR cycle threshold (tcdB Ct). We investigated the validity of this approach in an inpatient adult population.

Item Recognition Memory and the Receiver Operating Characteristic. [PDF]

Journal of Experimental Psychology: Learning, Memory, and Cognition, 2003
Four experiments were conducted to investigate the effects of study time, study repetition, semantic and orthographic similarity, and category length on item recognition memory receiver operating characteristics (ROCs). Analyses of ROC shape rejected A. P. Yonelinas's (1994) dual-process model.

Use of Receiver Operating Characteristic Curve to Evaluate a Street Lighting Control System

IEEE Access, 2021
Intelligent control of public lighting is nowadays one of the most challenging issues in smart city deployment. Lighting optimization entails a compromise between comfort, safety, and power consumption, affecting both vehicles and pedestrians.

A questionnaire to identify patellofemoral pain in the community: an exploration of measurement properties [PDF]

, 2016
Background Community-based studies of patellofemoral pain (PFP) need a questionnaire tool that discriminates between those with and those without the condition.

Risk assessment and receiver operating characteristic curves [PDF]

Psychological Medicine, 2011
Risk assessment is now regarded as a necessary competence in psychiatry. The area under the curve (AUC) statistic of the receiver operating characteristic curve is increasingly offered as the main evidence for accuracy of risk assessment instruments. But, even a highly statistically significant AUC is of limited value in clinical practice.

Policy regarding the sequential lineup is not informed by probative value but is informed by ROC analysis. [PDF]

, 2014
It is important to determine if switching from simultaneous to sequential lineups affects response bias (the inclination to make an identification from a lineup), discriminability (the ability to distinguish between innocent and guilty suspects), or both.
