| This thesis investigated the use of tables and graphs to present quantitative data at U.S. FDA drug advisory committee meetings. A total of 7, 422 slides presented at such meetings in 2010 comprised the sample. All slides were coded for slide type; slides displaying graphs were also coded for graph type. Analyses were conducted to determine differences in data presentation format between the FDA and drug sponsors, slides shown to different types of advisory committees, and slides shown at meetings held for different purposes.;The study found that tables and graphs are used in almost equal measure at drug advisory committee meetings. However, the FDA is more likely than drug sponsors to display data in tables versus graphs. The study also found that the most prevalent graph formats are bar graphs, forest plots, line graphs, and Kaplan-Meier curves. Only one slide, shown by a drug sponsor, displayed a pictograph. |
