Designing 2-Phase Prevalence Studies in the Absence of a "Gold Standard" Test [PDF]
American Journal of Epidemiology, 2009 A population survey for estimating prevalence is challenging when a disease or condition is difficult to diagnose. If clinical diagnosis is expensive, a 2-phase study, in which less expensive but less accurate tests are administered to all study subjects in the first phase (screening phase) and a more accurate but expensive or time-consuming test is ...

Interval estimation for the difference in paired areas under the ROC curves in the absence of a gold standard test [PDF]
Statistics in Medicine, 2009 Receiver operating characteristic (ROC) curves can be used to assess the accuracy of tests measured on ordinal or continuous scales. The most commonly used measure for the overall diagnostic accuracy of diagnostic tests is the area under the ROC curve ...

Meta‐analysis of dichotomous and ordinal tests with an imperfect gold standard [PDF]
Research Synthesis Methods, 2022 AbstractStandard methods for the meta‐analysis of medical tests, without assuming a gold standard, are limited to dichotomous data. Multivariate probit models are used to analyse correlated dichotomous data, and can be extended to model ordinal data. Within the context of an imperfect gold standard, they have previously been used for the analysis of ...
