Effective Matrix View of Attribute Data

In assisting a medical device company, Exponent personnel developed a unique Matrix chart to effectively use color-coding for presenting multi-dimensional attribute data. Our client, a medical device company, studied a group of patient who participated in treatment with the manufacturer’s medical devices in a series of clinical trials. The device in each trial has its uniqueness in design and type of material. Patients were selected to wear the device on left body part, right body part, or both. An adverse effect can occur in any scenario. The devices are produced in large, medium, and small sizes as indicated in color-coding in this chart. Letter L or R or 2 indicates that an adverse effect occurred on left or right body part or both side respectively. Letter O indicates no adverse effect. Our client has effectively used this matrix chart, as a dashboard view, to present such complex attribute data in meeting presentations and reports.
