Interventions compared in the included studies. ¹A third group received both survival and mortality curve. ²Eight interventions with variation of each format type were tested (3 pictographs, 2 bar graphs, 1 line graph, 2 pie graphs). ³Four interventions: 2 static (bar graph, pictograph) and 2 animated (bar graph, pictograph). ⁴Survival curves were delivered either in 5y or 15y worth data and the same for mortality curves. ⁵Four interventions were tested (4-options pictograph, 4-options bar graph, 2-options pictograph, 2-options bar graph). ⁶Two pictographs; a graph with survival only outcome versus a graph with multiple outcomes. ⁷The three formats were embedded in fact box format, two studies were reported one face to face and one online. ⁸Two conditions were tested in this study; only one contained prognostic information (middle ear infection) and was included. ⁹Two studies were reported (breast cancer screening, female participants) and (prostate cancer screening, male participants). Each study tested 3 interventions (pictograph, tabular, free text). X refers to a study group
