This toolkit supports research in infectious diseases through two complementary tools. TAG Minder is a terminology management system for the medical ontology that underpins automated meta-analysis workflows — use it to browse, refine, and correct the tags applied across datasets and analyses to ensure consistent, reproducible results. Value-DX is a clinical decision-support tool that computes evidence-based diagnostic pathways for community-acquired respiratory tract infections, integrating diagnostic test accuracy, costs, and local prevalence into re-computable decision trees.
