Abstract
Background: Diagnostic evidence of the accuracy of a test for identifying a target condition of interest can be estimated using systematic approaches following standardized methodologies. Statistical methods for the meta-analysis of diagnostic test accuracy (DTA) studies are relatively complex, presenting a challenge for reviewers without extensive statistical expertise. In 2006, we developed Meta-DiSc, a free user-friendly software to perform test accuracy meta-analysis. This statistical program is now widely used for performing DTA meta-analyses. We aimed to build a new version of the Meta-DiSc software to include statistical methods based on hierarchical models and an enhanced web-based interface to improve user experience.
Results: In this article, we present the updated version, Meta-DiSc 2.0, a web-based application developed using the R Shiny package. This new version implements recommended state-of-the-art statistical models to overcome the limitations of the statistical approaches included in the previous version. Meta-DiSc 2.0 performs statistical analyses of DTA reviews using a bivariate random effects model. The application offers a thorough analysis of heterogeneity, calculating logit variance estimates of sensitivity and specificity, the bivariate I-squared, the area of the 95% prediction ellipse, and the median odds ratios for sensitivity and specificity, and facilitating subgroup and meta-regression analyses. Furthermore, univariate random effects models can be applied to meta-analyses with few studies or with non-convergent bivariate models.
The application interface has an intuitive design set out in four main menus: file upload; graphical description (forest and ROC plane plots); meta-analysis (pooling of sensitivity and specificity, estimation of likelihood ratios and diagnostic odds ratio, sROC curve); and summary of findings (impact of test through downstream consequences in a hypothetical population with a given prevalence).
All computational algorithms have been validated in several real datasets by comparing results obtained with STATA/SAS and MetaDTA packages.
Conclusion: We have developed and validated an updated version of the Meta-DiSc software that is more accessible and statistically sound. The web application is freely available at www.metadisc.es.

Funding Information:Meta-DiSc 2.0 has been developed with funding from an intramural project by the Ramón y Cajal Research Institute ("Rapid diagnostic reviews for decision-making in healthcare: analysis of critical points and software development", 2018). It has also been funded by Instituto de Salud Carlos III through the project "PI19/00481" (Co-funded by European Regional Development Fund/European Social Fund; “A way to make Europe”/"Investing in your future"). The Biomedical Research Networking Center in Epidemiology and Public Health (CIBERESP) funds the subscription to the shinyapps.io platform where the app is hosted. The funding body played no role in the design of the study and collection, analysis, and interpretation of data and in writing the manuscript.
