This image presents a risk estimate to a patient, and more importantly, it also shows them how much that risk could be reduced. It uses an icon array display, which research has shown is a particularly effective type of graphic at showing risk but which needed new thinking about how to show risk reduction.

What’s special about this image?

This display uses three cues to highlight particular icons in a dot array: icon size, icon color, and background shading.

One weakness is that this design would have problems labeling larger levels of risk (e.g., 55% reducing to 35%) because the labels are closely aligned with the height of the first column of icons.
