At present, a variety of noninvasive tests having different specificities and sensitivities are available for the diagnosis of visceral ...
متن کاملStatistical methods for multivariate meta-analysis of diagnostic tests: An overview and tutorial.
In this article, we present an overview and tutorial of statistical methods for meta-analysis of diagnostic tests under two scenarios: (1) when the reference test can be considered a gold standard and (2) when the reference test cannot be considered a gold standard. In the first scenario, we first review the conventional summary receiver operating characteristics approach and a bivariate approa...
متن کاملMeta-analyses of diagnostic studies.
BACKGROUND Diagnostic reviews often include the sensitivity/specificity results of individual studies. A problem occurs when these data are pooled because the correlation between sensitivity and specificity is generally strongly negative, causing overestimation of the pooled results. The diagnostic odds ratio (DOR), defined as the odds of true positives vs. that of false positives, may avoid th...
متن کاملComparative evaluation of blood and serum samples in rapid immunochromatographic tests for visceral leishmaniasis.
Rapid diagnostic tests (RDTs) based on the detection of specific antibodies in serum are commonly used for the diagnosis of visceral leishmaniasis (VL). Several commercial kits are available, and some of them allow the use of whole-blood samples instead of serum. An RDT is much more user-friendly for blood samples than for serum samples. In this study, we examined the sensitivities and specific...
