Visualizations aid in communication / presentation (+) Positive One or more sentences p. 6 «They also can aid the comprehension of more complicated concepts such as incremental risk.»
Visualizations aid in communication / presentation (*) Mentioned without valuation One or more sentences p. 6 «The communication of epistemic uncertainty has been examined in a small number of studies using confidence intervals to communicate ambiguity in probability estimates. These studies have shown that communicating ambiguity has little effect on risk perceptions, although it increases patient worry, and these effects appear to be moderated by representational method (visual vs. textual) and individual differences (e.g., dispositional optimism).»
Visualizations are animated (+-) Ambivalent One or more subsections p. 10 «However, evidence is lacking to determine whether the techniques allowed by new technologies provide a net positive experience. Preliminary evidence suggests that, unless the motion cues reinforce the most critical gist message (e.g., the accumulation of risk over time), there remains significant risk that interactive or animated formats may degrade knowledge versus evidence-based static formats.»
Visualizations are discrete (+) Positive One or more sentences pp. 6–7 «Enhancing accuracy in estimates can be aided by displaying only the most crucial elements…»
Visualizations are open for interaction (+-) Ambivalent One or more subsections p. 10 «However, evidence is lacking to determine whether the techniques allowed by new technologies provide a net positive experience. Preliminary evidence suggests that, unless the motion cues reinforce the most critical gist message (e.g., the accumulation of risk over time), there remains significant risk that interactive or animated formats may degrade knowledge versus evidence-based static formats.»
Visualizations group information (+-) Ambivalent One or more sentences p. 7 «…as well as by using icon arrays (blocks or stick figures) that are arranged as groups in a block rather than being scattered randomly – the latter of which is useful to convey the concept that events (e.g., who is afflicted by disease) occur at random.»
Visualizations help overcome cognitive biases (+) Positive One or more sentences p. 6 «Visual displays can help reduce several biases, such as denominator neglect, framing effects, and the undue influence of anecdotes.»
Visualizations help overcome cognitive biases (+) Positive One or more sentences p. 4 «Visual formats may also help to reduce bias.»
Visualizations integrate views/data (+) Positive One or more sentences p. 8 «Given these findings and current limitations in evidence, a balanced approach using both survival and mortality graphs may be prudent until more information is available.»
Visualizations make information understandable (+) Positive One or more sentences p. 6 «Presenting event rates with visual aids such as pictographs (also called icon arrays), bar charts, or flow diagrams may aid accurate understanding of probabilities.»
Visualizations make information understandable (?) Questioned One or more sentences p. 6 «…one important caveat is that people vary in their ability to extract data and meaning from visual displays.»
Visualizations make information understandable (?) Questioned One or more sentences p. 6 «However, there has been some evidence that graphs can affect peoples’ tendencies to overestimate low probabilities and underestimate high probabilities – the magnifier effect. Others have shown the opposite effect (i.e., less overestimation) on low probabilities and no effect on high.»
Visualizations promote adoption of analytical methods (+) Positive One or more sentences p. 6 «Graphs that clarify sub-set relationships (e.g., Venn diagrams, Euler circles) can lead to better judgements, for instance in Bayesian reasoning tasks. Others believe graphs help, but for different reasons.»
Visualizations provide an additional explanation (+) Positive One or more sentences pp. 8–9 «They found that, when statistical information was reinforced with pictographs and quizzes, anecdotes had no significant effect on treatment decisions. The same authors also found pictographs were the active ingredient that lessened the effect of anecdotes. This finding would argue for avoiding narratives without statistical information.»
Visualizations provide context (+) Positive One or more sentences p. 7 «Finally, it has been shown that visual aids are most effective for comprehension when the entire population at risk is shown rather than only depicting sick people, for instance.»
Visualizations provide context (-) Negative One or more sentences p. 8 «When web-users were shown survival graphs for a hypothetical disease and treatment, they based their perceptions of treatment effectiveness on visual differences in these graphs. When a longer duration of data was shown, people perceived larger differences in risk even when the magnitude of risk reduction was identical.»
Visualizations retain complexity (+) Positive One or more sentences p. 8 «A study presenting treatment options for esophageal cancer showed most patients understood graphical representations of even complex multidimensional patient-reported outcomes.»
Visualizations show visual patterns (+-) Ambivalent One or more sentences p. 6 «Thus, a potential weakness of visual displays is that people may focus more on the pattern of data rather than the precise values, unless that is the main objective.»
