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.

What’s special about this image?

This adaptation of a vertical bar graph uses a callout to clarify the risk reduction while still showing that all of these risks are quite small (the vast majority of people do not die of colon cancer).

Note that an unintentional typographic error labels the risk after screening tests as 1.7% instead of the correct 1.8%.
