This display tries to help patients compare their current risk withoutscreening tests versus their reduced risk if they have screening tests. In particular, it aims to help patients understand the absolute size of the possible risk reduction.
This number line graphic uses a magnified callout (representing the first 15% of the full 0-100%) to clarify the difference that regular screening tests achieve in cancer risk.
Note that the colored bars are fully replicated (on a smaller scale) in the full number line. This helps people see the full part-to-whole relationship between cancer events and the population as a whole.
