The Value of Serodiagnosis of Helicobacter pylori in Predicting Negative Gastroscopy [PDF]

, 1994
Increasing constraints with escalating demands on endoscopy resources have prompted interest in evaluating ways of predicting clinically non-significant endoscopies. Previous systems have attempted to identify high-risk patients by collating known predisposing factors to ulcer disease.

Comparison of mammography and breast infrared imaging: sensitivity, specificity, false negatives, false positives, positive predictive value and negative predictive value

Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015), 2003
Breast infrared imaging (IRI) for detection of breast cancer has been unfairly maligned as having unacceptably high false positive and false negative rates. IRI actually has statistical performance characteristics that are similar to mammography. The false positive rate of 14% is about twice as high as mammography but surgical intervention is not ...

What is the clinical value of negative predictive values of skin tests to iodinated contrast media?

Allergy and Asthma Proceedings, 2016
Iodinated contrast media (ICM) can cause hypersensitivity reactions (HSR), yet data are scant about the negative predictive value (NPV) of ICM skin tests.To determine the NPV of skin tests to ICM Methods: We enrolled 73 patients with a history of HSRs to ICM, 136 subjects with no previous exposure to ICM, and, as controls, 47 subjects who had ...

RADIOGRAPHIC SENSITIVITY AND NEGATIVE PREDICTIVE VALUE FOR ACUTE CANINE SPINAL TRAUMA

Veterinary Radiology & Ultrasound, 2006
The objectives of this study were to establish the sensitivity and negative predictive value of radiography for acute spinal osseous lesions in the canine trauma patient, and to evaluate the interobserver variability in radiographic assessment of the spine in traumatized dogs. This was a retrospective multiple observer blinded study.
