Publication information
Reading at your pace
The layout keeps evidence, measured outcomes and limits available in the document.
Readable text
Main reading text begins at 22 pixels and can be enlarged to 26 pixels with the Larger text button. Browser zoom remains available. The two evidence fields become a single consecutive column on narrow screens, with the relevant boundary immediately following.
Keyboard and source navigation
Use the first skip link to reach the main content. Underlined source-topic and return links use normal browser navigation; their headings can receive focus. Sources and related reading remain open, including when JavaScript is unavailable.
Controls with a limited purpose
The library’s labelled search and type controls organize articles. Larger text changes presentation. Neither control makes a medical assessment. The source reader does not require hovering, dragging, animation, a timed step or a personal answer.
