The focus on digital versions of medical journals is increasing, but audiences still benefit from the printed versions. Practically, however, the amount and types of information that can be printed – word count and number of figures or tables – are limited and, ultimately, ‘static’. Considering the ever-increasing complexity of clinical topics that health professionals and patients are exposed to, this limitation decreases the chances of providing more comprehensive or innovative explanations of complex findings. Additionally, the two‑dimensional representation of information is not always suitable when illustrating complex structures, functions or interrelationship of concepts.
