Pretest probability assessment derived from attribute matching

Pretest probability assessment derived from attribute matching

BACKGROUND Pretest probability (PTP) assessment plays a central role in diagnosis. This report compares a novel attribute-matching method to generate a PTP for acute coronary syndrome (ACS). We compare the new method with a validated logistic regression equation (LRE). METHODS Eight clinical variables (attributes) were chosen by classification and regression tree analysis of a prospectively c...

Value of assessment of pretest probability of deep-vein thrombosis in clinical management.

BACKGROUND When ultrasonography is used to investigate deep-vein thrombosis, serial testing is recommended for those who test negative initially. Serial testing is inconvenient for patients and costly. We aimed to assess whether the calculation of pretest probability of deep-vein thrombosis, with a simple clinical model, could be used to improve the management of patients who present with suspe...

Renal angina: concept and development of pretest probability assessment in acute kidney injury

The context of a diagnostic test is a critical component for the interpretation of its result. This context defines the pretest probability of the diagnosis and forms the basis for the interpretation and value of adding the diagnostic test. In the field of acute kidney injury, a multitude of early diagnostic biomarkers have been developed, but utilization in the appropriate context is less well...
