Initial user testing, however, did not support the utility of such graphical displays. Conclusionsįishbone diagrams are compact visualizations that, theoretically, may prove useful for summarizing the findings of systematic reviews. However, more than half of the participants in both groups were unable to find critical information and answer three respective questions correctly (52.6% in the fishbone group 51.3% in the summary of findings group). 35.9%, p < .05) or indicated that it was difficult to find information (65.8% vs. 44.8% p < .01) significantly more participants found the fishbone diagram confusing (63.2% vs. Significantly more participants liked the summary of findings table than the fishbone diagram (71.8% vs. User testing on 77 students with basic epidemiological training revealed that participants preferred summary of findings tables over fishbone diagrams. Resultsīased on real world systematic reviews, we provide two different fishbone diagrams to show how they might be used to display complex information in a clear and succinct manner. We analyzed quantitative data by conducting t-tests and comparing descriptive statistics. We asked respondents about the perceived utility of fishbone diagrams compared to summary of findings tables. Measures of interest focused on first and second impressions, the ability to find and interpret critical information, as well as user experience with both displays. They answered questions in both open-ended and closed-answer formats all responses were anonymous. Respondents were randomized to the fishbone diagram or a summary of findings table presenting the same body of evidence. To test the utility of fishbone diagrams compared with summary of findings tables, we developed and pilot-tested an online survey using Qualtrics. Methodsįindings from two systematic reviews were graphically depicted in the form of the fishbone diagram. In this paper we demonstrate how fishbone diagrams can be applied to systematic reviews and present the results of an initial user testing. The usage of fishbone diagrams as graphical displays could offer researchers an effective approach to simplify content for readers with limited epidemiological training. Summary of findings tables in systematic reviews are highly informative but require epidemiological training to be interpreted correctly.
