Author Management
General Information

Where can I enter a sponsorship or funding statement for my abstract?

There is no separate field to indicate a sponsorship or funding statement for an abstract. If such a sponsorship exists, please add it under the presenting author’s CoIs, under the section “Others”. E.g. “Other: Sponsor of Study: Company XYZ”

Conflict of Interest (CoI) Management
Disclosure of Conflicts of Interest Statement

As of ECCO’26, all abstracts will be published with the respective Conflicts of Interests (CoI) for each Co-Author.

To simplify the procedure of uploading the CoIs, a new feature has been added to the submission process. When adding each co-author, a check can be run via the ECCO database, if the co-author has already submitted CoIs in their profile. 

Please inform the ECCO Office in case there are any technical issues or if you have any queries about this process.

General Information

• For each co-author the CoI information must be provided. In case you cannot move on from the co-author page, please double-check for each author if the CoI field is filled.
• Each delegate who has a profile with the ECCO portal can update their CoI information via the ECCO Portal. The collection period will be from beginning of September 2025 to November 3, 2025. Then the ECCO profiles will be locked and CoI information cannot be entered anymore.

How can I add co-authors and have their CoIs included?

To add a co-author, please enter their Names and E-mail address. To continue with the check, you can click on find author.

A pop-up window will appear with existing entries from the ECCO database. If an exact match has been found, you will see the full email address. In this case, please select the author and click on “” 

With this step, the author’s credentials are being taken over automatically.
If the added co-author does not have CoIs in their profile, please enter the CoI information manually in the respective text box.

In case the co-author has no conflicts, please click the “No conflicts” button. 

Don’t forget to click “Save co-author”, to add the author to the co-author’s list.

 

The entered E-Mail address is not showing up?

The search is based on the entered email address and not the name. If no perfect match is found for the E-Mail address, the system will suggest similar entries.

In this case, please click on “” and enter the co-authors details manually.

My co-author is not listed in the overview?

In case your co-author is not listed in the pop-up box, you can still add all details manually.

Please make sure to fill in the Institute, Department, City & Country, as well as the Conflicts of Interests accordingly.

There is no pop-up window opening when searching for the authors?

In case there is no entry in the database, the pop-up window will not open. In this case please continue as well with the manual entry of all the data.

I cannot proceed from the co-authors page?

As a submitting author you are required to review and confirm your own CoI information. In case you did not do this step, a pop-up window will open reminding you to do so. 

Please follow the instructions as shown above.

Image Upload

By clicking on this icon, a pop-up window will open. First step is to upload the respective images via the button upload.
