The reviewed literature recommends presenting some types of information using the rational (fact-based) style, which means presenting the health message (piece of information or the risks in the prototype) using abstract symbols, words, and numbers.
These guidelines were used to present some parts of the initial prototypes (i.e. risks) and they proved to be effective as per the eye tracking experiment. In this experiment, it was found that participants understood the information about disease slightly more if it was written using rational (fact-based) style.
The stakeholders supported this approach and recommended that information on the report needs to be well based on facts. The English speakers group also supported these guidelines, as patients in the focus groups preferred the messages to be presented as a fact-based accompanies with pictures. However in the GP trials much of the narrative information was cut on recommendation of the GP focus groups. Results from the trials indicated that this way of presenting was well understood and acceptable.
Therefore, it is preferable to present some relevant parts or risks (e.g. stroke/heart attack) fact-based style.
