Evaluation of a rapid test for the diagnosis of cholera in the absence of a gold standard.
PLoS ONE, 2012 BackgroundEarly detection and confirmation of cholera outbreaks are crucial for rapid implementation of control measures. Because cholera frequently affects regions with limited laboratory resources, rapid diagnostic tests (RDT) designed for field ...

On the robustness of latent class models for diagnostic testing with no gold standard
Statistics in Medicine, 2021 It is difficult to estimate sensitivity and specificity of diagnostic tests when there is no gold standard. Latent class models have been proposed as a potential solution as they provide estimates without the need for a gold standard. Using a motivating example of the evaluation of point of care tests for leptospirosis in Tanzania, we show how a ...

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 ...

A studentized permutation test for three‐arm trials in the ‘gold standard’ design [PDF]
Statistics in Medicine, 2016 The ‘gold standard’ design for three‐arm trials refers to trials with an active control and a placebo control in addition to the experimental treatment group. This trial design is recommended when being ethically justifiable and it allows the simultaneous comparison of experimental treatment, active control, and placebo. Parametric testing methods have
