Expert Journal(TM) is Transporins flagship product in expert clinical knowledge management. The unit of knowledge is the retrospective ("Retro") which provides, for the first time, specific visual and compact data comparisons of key clinical data from paired studies. The images are rendered on-the-go, on mobile devices fully integrated with Twitter(TM) and FaceBook(TM), providing real-time access. It is a way to provide every user with the specific data comparisons upon which experts typically base their decisions. Each retro is deemed particularly important by a respected opinion leader in the relevant clinical field.
