Table 1 Main concepts and features of the EDAs. Adapted from Heen et al. (2021) [19]

- Electronic generic framework for decision aids integrated in an authoring and publication platform for guidelines and evidence summaries (MAGICapp)

- Decision aids are semi-automatically produced and updated based on content in MAGICapp with adaptation possibilities (e.g. wording and number of outcomes, language)

- Multi-layered presentation format:

 ○ First layer displays the list of patient-important outcomes and practical issues. (Fig. 2)

 ○ Second layer displays interactive outcome cards with evidence estimates, certainty, and patient-important practical issues across 15 generic categories. Possibility to interactively compare two or more outcomes in parallel. (Fig. 3)

 ○ Third layer displays a corresponding set of pictographs showing the absolute risk with each option (Fig. 4) and practical issues related to the treatment option (Fig. 5)

- Educational module developed http://magicproject.org/161128/ and integrated in MAGICapp. This module was not used in our study, yet could be accessed by the GPs on their own

- Print functionality of decision aids create pdf files that can be printed or used for notetaking and/or to bring home

- Prototype for comparisons between multiple options are developed and implemented in a BMJ Rapid Recommendation

- Offline feature so decision aids can be used without use of Internet

- Widgets from MAGICapp to grab and show a given decision aid on any other online platform. Example: Rapid Recommendation on Prostate cancer screening (https://www.bmj.com/content/362/bmj.k3581 to BMJ infographic) which links to MAGICapp content, including widgets to decision aids for various profiles of patients
