Predictive Value of a Negative Exercise Electrocardiogram

Cardiology, 1991
Conventionally, if an exercise electrocardiogram does not show evidence of ischemia, the patient must have achieved at least 85% of the predicted maximum heart rate for that test to be considered negative. However, no documentation of the validity of this practice exists.

Using Negative Predictive Values: In Reply

Pediatrics, 2006
In Reply .— We appreciate Dr Camp's comments and her emphasis of the importance of the high negative predictive value of the Bayley Mental Developmental Index (MDI). We agree that a normal MDI of >85 at 20 months' corrected age in an extremely low birth weight (ELBW) child is highly predictive of having a normal IQ of >85 at 8 years of age …

The Negative Predictive Value of Typing Safe Local Anesthetics

International Archives of Allergy and Immunology, 2013
<b><i>Background:</i></b> Although allergy to local anesthetics (LA) is rare, patients often report unwanted reactions after their administration. A history of anaphylaxis or an atypical reaction related to LA is an indication for typing a safe anesthetic for future surgical or dental procedures. <b><i>Aim:</i>&

Using Negative Predictive Values

Pediatrics, 2006
To the Editor .— In “Poor Predictive Validity of the Bayley Scales of Infant Development for Cognitive Function of Extremely Low Birth Weight Children at School Age,”1,2 we learn that things have not changed in the last 40 years. Early mental tests are still poor predictors of later intelligence,3 and normality at early ages is a better predictor of ...

Negative predictive value of drug provocation tests in children

Pediatric Allergy and Immunology, 2014
AbstractBackgroundThe negative predictive value of the drug provocation test is important for both the patient and the physician. However, in children, this predictive value is unresolved.MethodsThe study included patients who had drug provocation test with a suspected drug and was diagnosed as ‘not allergic to the drug’.

Negative predictive value of procalcitonin in medullary thyroid carcinoma

Annales de biologie clinique, 2016
Calcitonin (CT), the major biochemical marker in medullary thyroid carcinoma (MTC) is prone to in vitro instability and suffers from scarcity of clinical laboratory platforms. Procalcitonin (PCT), the precursor of CT, free of these shortcomings, has been reported as a potential MTC marker.

Binary regression: Total gain in positive and negative predictive values

Biometrical Journal, 2012
Models that predict disease incidence or disease recurrence are attractive for clinicians as well as for patients. The usefulness of a risk prediction model is linked to the two questions whether the observed outcome is confirmed by the prediction and whether the risk prediction is accurate in predicting the future outcome, respectively.
