Published ECCO Guidelines
In its aim to foster transparency, ECCO has diligently maintained a disclosure policy of potential conflicts of interests (CoI) for several years: ECCO Guidelines manuscripts cannot be submitted for publication without all authors having submitted their CoI Forms.
As ECCO experts are increasingly involved in several activities such as the ECCO Congress, Workshops, Guidelines, or other projects, including publications of papers in JCC (Journal of Crohn’s & Colitis) throughout one year, ECCO now collects one completed CoI form from experts in line with the respective Congress business year (updated every autumn). These forms are publically accessible through the ECCO website – showing the “ECCO Annual Disclosure of potential conflicts of interest”.
