Diagnostic tests: how to estimate the positive predictive value [PDF]
Abstract When a patient receives a positive test result from a diagnostic test they assume they have the disease. However, the positive predictive value (PPV), ie the probability that they have the disease given a positive test result, is rarely equal to one.

The predictive value of prenatal cell-free DNA testing for rare autosomal trisomies: a systematic review and meta-analysis [PDF]
Objective: The diagnostic accuracy of cell-free fetal DNA in screening for rare autosomal trisomies is uncertain. We conducted a systematic review and meta-analysis aiming to determine the predictive value of cell-free DNA in screening for rare autosomal

An invalidation test for predictive models [PDF]
The standard means of establishing predictive ability in hydrological models is by finding how well predictions match independent validation data. This matching may not be particularly good in some situations such as seasonal flow forecasting and the ...

Evaluation of the 50th percentile Moyers analysis in patients with permanent dentition
Background: the 50th percentile values from the Moyers table, used in Cuba, does not always correspond to the mesiodistal diameter of erupted canines and premolars, for which it is necessary to adjust the probability levels to the studied population ...
