Predictive value of serologic tests. [PDF]
An analysis of serologic tests for treponemal disease performed in Australian aboriginal communities is used to illustrate factors influencing the predictive value positive of serologic tests. Simple extrapolation of predictive value estimates, from prevalence, sensitivity, and specificity data, is complicated by variation of specificity between ...

Positive predictive value of tests for breast disease [PDF]
EDITOR,—J M Dixon and R E Mansell attempt to clarify the utility of various diagnostic tests for symptomatic breast diseases.1 Unfortunately, their use of the positive predictive value in this context is misleading since it can refer only to the ...

Machine Learning in Falls Prediction; A cognition-based predictor of falls for the acute neurological in-patient population [PDF]
Background Information: Falls are associated with high direct and indirect costs, and significant morbidity and mortality for patients. Pathological falls are usually a result of a compromised motor system, and/or cognition. Very little research has been conducted on predicting falls based on this premise.

Predictive value of perioperative gastric acid tests. [PDF]
Preoperative acid studies and early postoperative insulin tests in 275 patients undergoing various forms of vagotomy have been related to recurrent ulceration. Follow-up time has been from two to nine years, mean 4-3 years. Recurrence is directly related to basal acidity in both tests but is not related to stimulated acid levels preoperatively.

Comparison of predictive values with paired samples [PDF]
Positive predictive value and negative predictive value are two widely used parameters to assess the clinical usefulness of a medical diagnostic test. When there are two diagnostic tests, it is recommendable to make a comparative assessment of the values of these two parameters after applying the two tests to the same subjects (paired samples).

Development of a simple nomogram to estimate risk for intraoperative complications before partial nephrectomy based on the Mayo Adhesive Probability score combined with the RENAL nephrometry score [PDF]
Purpose: This study aimed to develop a simple nomogram based on the Mayo Adhesive Probability (MAP) score combined with the RENAL nephrometry score (RNS) to predict intraoperative complications before partial nephrectomy (PN) in Asian populations ...
