OBJECTIVE Radiology is the specialty of imaging-based diagnostic tests. Understanding the science behind evaluating diagnostic test performance is essential for radiologists because we provide care to patients and interact with our colleagues. CONCLUSION Here, we review the key terminology used and common pitfalls encountered in the literature and in day-to-day discussions of diagnostic test ...

In 2 experiments, the authors investigated a potential interaction involving the processing of concurrent feedback using design features from the specificity of practice literature and the processing of terminal feedback using a manipulation from the guidance hypothesis literature. In Experiment 1, participants produced (198 trials) flexion-extension movements to reproduce a specific pattern of...

Background. Coexistence of pain and depression has significant impact on the patient's quality of life and treatment outcome. DoloTest is a pain and HRQoL assessment tool developed to provide shared understanding between the clinician and the patient of the condition by a visual profile. Aim. To find the sensitivity and specificity of DoloTest as a screening tool for depression for patients in ...

This study determined whether the orientation of dorsoplantar and oblique foot radiographs has an effect on radiograph interpretation. A test set of 50 consecutive foot radiographs were selected (25 with fractures, and 25 normal), and duplicated in the horizontal orientation. The images were randomly arranged, numbered 1 through 100, and analysed by six image interpreters. Vertical and horizont...

Currently, a gold standard for distinguishing between infectious, inflammatory, auto-immune diseases and malignancy in infants and children is not available. The combination of biomarkers with clinical features and other diagnostic tests could help clinicians in the diagnostic process. Ideally, a biomarker should have high sensitivity, specificity, and predictive value, as well as being easily ...

A postal questionnaire was introduced as a screening procedure for a comprehensive geriatric assessment programme in general practice. It had a response rate of 81 per cent, a sensitivity of 0.95, a specificity of 0.68, and a predictive value of 0.91. The use of this screening procedure could reduce the workload of an assessment programme by one fifth.

OBJECTIVE This case series examines the feasibility, specificity, and preliminary effectiveness of NeuroGame Therapy (NGT) for improving wrist control in four children with cerebral palsy (CP). NGT uses surface electromyographic (sEMG) signals routed through motivating computer games to improve motor control. METHODS Primary outcomes of NGT included feasibility (hours of play) and specificity...

The specificity and sensitivity of a quantitative diagnostic test depends on the chosen cutoff point. The common practice of selecting a cutoff point that maximizes the specificity plus the sensitivity, as judged from the observed test results, is studied here by simulation. Test performance is on average assessed too optimistically by this procedure--a phenomenon of importance when sample size...

1st para: It is now considered good reporting practice to avoid labeling individuals with their disease or disability. E.g. “chronic haemodialysis patients”. A more appropriate description could be “patients on chronic HD”. Please consider changing throughout. We changed the description of the patients throughout the paper. The abstract lacks specificity and as currently reads, cannot stand on ...
