  13. Which is the perspective of an abstract ? • To be presented on scientific meetings • Oral presentation • Poster presentation • To be cited as an abstract • To be written in a peer reviewed journal • To be cited as a paper

  14. Example of not well documented abstract

  19. Conclusions • The majority of published abstracts does not comply with evidence based medicine • It is of paramount importance to innitiate a correct study design • Avoidance of studies with retrospective and historical nature • Prospective studies are mandatory and preferred • Every abstract has to be viewed as a highly cited paper in a peer reviewed journal

  20. CODA • Accepting reseach in our centers based on • pilot studies • prospective studies • randomized controlled trials • This type of research does not encounter competition • High acceptance rates of abstracts and manuscripts are predictable • Randomized controlled trials (RCT) are proned to be cited in meta-analysis
