This display represents the relative likelihood and severity of multiple side effects in a tabular structure. It also organizes this information to ensure that viewers pay attention to very rare but very severe events and represents whether risk numbers are based on general population samples or are tailored by characteristics such as age, gender or race.
This hybrid graphic uses a matrix of pie charts to organize information about side effect risks while allowing for easy focusing on individual risks. Severity is shown by color, while likelihood is shown by number and pie wedge size. In addition, risks are ordered in the matrix (left to right, top to bottom) in order of increasing likelihood. Personalization of the information is subtly shown via the blue outlines and text for the two risks in the middle.
Based on our testing, this graphic helped explain basic risk numbers but did not draw people's attention to the risks that are based on more personalized data. However, in follow-up testing this type of table performed less well than tables with embedded icons
