Because patients can have poor understanding of outcomes related to total knee replacement (TKR) surgery, Fraenkel et al. studied the impacts of different presentation formats in patients’ understanding of TKR outcomes. 648 members of an online arthritis network participated in this study and were randomly assigned to one of the following presentation groups: numeric only, numeric with an icon array, numeric with a set of 50 images, or numeric with a functional spinner. Preferences for TKR were measured before and immediately after viewing the presentation and knowledge was assessed for each participant. The authors found that adding graphic information to descriptive statistics strengthens preference for TKR.
