Abstention from Voting

As in other ESC guidelines, no detailed information is provided regarding the process of drafting the guideline. Consequently, we do not know whether authors with conflicts of interest participated in any voting relevant to their conflicts.

Overall score


Good! (11-18)

Warning! (6-10)

Needs reform! (0-5)


As in the ESC guidelines previously evaluated by Leitlinienwatch the majority of the authors (92 percent) have a conflict of interest. Additionally, no information is provided regarding how the recommendations were drafted or whether authors with conflicts of interest voted on issues related to their conflicts of interest. Thus, the ESC guideline process is in urgent need of reform.
