Clinicians and applied researchers in medicine, education, psychology, criminal justice, and a host of other fields use meta-analysis to determine which interventions work, and.

report a single pair of sensitivity and specificity, but a full ROC curve with. Pharmaceutical companies use meta-analysis to gain approval for new drugs, with regulatory agencies sometimes requiring a meta-analysis as part of the approval process. It has already been used and cited in several meta-analyses published in high-ranking journals. Meta- analysis for diagnostic accuracy trials, however, has been a vivid. Additional analysis A small group of studies analyzed the accuracy of quotation of a specific source article (as opposed to the prevailing design of investigating the accuracy of quotations to.
For analysis we used Excel, Open Meta Analyst, and Comprehensive Meta Analysis, Version 2. CONCLUSION: Meta-DiSc is a comprehensive and dedicated test accuracy meta-analysis software. the main analysis in order to test the robustness of results. Meta-DiSc has a Graphical User Interface with roll-down menus, dialog boxes, and online help facilities.
All computational algorithms have been validated through comparison with different statistical tools and published meta-analyses. previously reported meta-analytical prognostic accuracy is not completely accurate. RESULTS: Meta-DiSc a) allows exploration of heterogeneity, with a variety of statistics including chi-square, I-squared and Spearman correlation tests, b) implements meta-regression techniques to explore the relationships between study characteristics and accuracy estimates, c) performs statistical pooling of sensitivities, specificities, likelihood ratios and diagnostic odds ratios using fixed and random effects models, both overall and in subgroups and d) produces high quality figures, including forest plots and summary receiver operating characteristic curves that can be exported for use in manuscripts for publication. A systematic review and meta-analysis of diagnostic test accuracy (DTA) aims to identify and summarise evidence on the accuracy of tests, including an assessment of the quality and consistency of the evidence.
#Comprehensive meta analysis accuracy software
In this article, we present Meta-DiSc, a Windows-based, user-friendly, freely available (for academic use) software that we have developed, piloted, and validated to perform diagnostic meta-analysis. Many test accuracy studies are small,2 and even when studies are large, the number of cases may be small due to the low prevalence of the target condition. However, there is currently no dedicated and comprehensive software for meta-analysis of diagnostic data. BACKGROUND: Systematic reviews and meta-analyses of test accuracy studies are increasingly being recognised as central in guiding clinical practice.
