RESEARCH SHOULD
BE READABLE.
Accessible navigation, visible controls, reduced motion, and an explicit route for reporting a problem.
Built for usable navigation
This release includes a skip link, semantic headings, keyboard-operable controls, visible focus states, labeled form fields, a mobile menu, descriptive image alternatives, and reduced-motion support for the cellular concept visualization.
Tables and calculators
Wide evidence tables scroll horizontally rather than shrinking text to unreadable sizes. Calculator errors are displayed near the result and announced through accessible status regions. Methods and assumptions remain available as ordinary text.
Known limits
The moving cellular illustration is conceptual and is not needed to understand the page. The interface has been built with accessibility features, but this statement is not a certification of conformance or a claim of an independent accessibility audit.
Report an issue
Use the contact page to describe the page, browser or assistive technology, and the action that caused difficulty. Do not send sensitive health information.
