Help & Feedback

* Some of the information on the site is incorrect or unclear. How can I get this fixed? *

Please let us know urgently via the feedback form. In the “type of request” drop-down select “Content / algorithm inaccurate” and we will ensure it is treated with the highest priority. You can also contact Julia at the ECCO office directly on

Browser support: if the site does not look good on your browser/phone etc...

The e-Guide currently supports “modern” browsers, including Internet Explorer 9+, Google Chrome & Firefox. Standard browsers for Android & iOS mobile devices are also supported. We are working on adding full support for Internet Explorer 8 and (possibly) Internet Explorer 7, according to need.
At present the e-Guide is designed primarily to work on desktop computers and tablets. Algorithms should be visible on mobile phones, but the site is not specifically optimized for these at present.

Can I use the e-Guide offline? Is the e-Guide available as a mobile app?

The e-Guide is currently only available online. However we are looking to develop an offline version and/or mobile app in the future.

How can I get involved in the team that works on the e-Guide?

If you would like to get involved, please let us know on the feedback form. This will notify the ECCO office of your interest.

How do I add a resource to the e-Guide?

At the moment all resources must be reviewed by the e-Guide team. There is a form available in the resource section that allows you to suggest a resource to the ECCO team. You can attach you proposed resource directly to this form, or provide a web link.

How do I log-in to the e-Guide?

As of February 2015, the ECCO e-Guide is now open access. You do not need to be an ECCO member to access the e-Guide.

How have the algorithms been developed?

The e-Guide is based on the ECCO Consensus Guidelines. A team of contributors developed and reviewed the visualization of these guidelines as algorithm. 

How have you calculated the data for risk & benefit visualizations?

Risk and benefit visualizations rely on data from individual clinical trials or meta-analyses.
When data is based on an individual clinical trial, we visualize particular efficacy or safety data by converting the % of study patients experiencing a benefit or risk into an absolute benefit/risk to 1,000 and 10,000 people. We are visualizing this data compared to placebo, except where stated, so the charts only show the treatment effect. We may look to include the benefit/risk from placebo and/or natural course of disease in future.
When the visualization is based on a meta-analysis, we will have converted either a number needed to treat (NNT) or an absolute risk reduction (ARR) into an absolute benefit/risk to 1,000 and 10,000 people. Many meta-analyses only provide relative risk data between two treatments, in which case we would not include this data in our visualization.

How up-to-date are the algorithms?

At the bottom of each algorithm it states when the algorithm was last revised. ECCO statements are the latest statements available at the time of this revision. These are currently 2014 statements except where explicitly stated.

I have a great idea for improving the e-Guide. Who do I tell?

We are looking to continuously improve the e-Guide over the coming months & years. You can share your ideas with the ECCO office and e-Guide developers via the feedback form

I think an algorithm can be improved. Who do I tell?

Our aim is to continuously improve the e-Guide over the coming months. If you would like to get involved, let us know on the feedback form. This will notify the ECCO office of your interest.

I think one of the resources on your site breaches my copyright. Who do I notify?

If you believe that one of our resources breaches your copyright, please notify us immediately via the feedback form. We will review your claim in a timely fashion and may take down the resource in accordance with our internal procedures.

Is there an easy way to print the algorithms? They don’t seem to print well.

We know about this issue and it is next on our to-do list. We expect to have downloadable and printable pdfs of the algorithms available shortly.

I’ve found a bug in the site. Who do I tell?

Please let us know via the feedback form. In the “type of request” drop-down select “Technical issue”.

The algorithms look a bit "squashed" when I view them on my phone. Can I improve how they look?

We have optimized the site for desktop and tablet devices, such as iPads. However displaying algorithms clearly on the typical screen size of a mobile phone is a little trickier. As such you may have to zoom in and out to navigate the algorithms fully. We will continue to work on this in the future.

What are the sources of information used in the e-Guide?

The e-Guide is based on the ECCO Consensus Guidelines, as well as on original studies referenced in the guidelines. While we have always aimed to base content on the guidelines, there is inevitably some degree of expert interpretation required and details of the contributor team can be found on the About page. The latest ECCO statements (currently 2014) are used except where specified.

What do the different colours on the algorithm mean?

In general, red boxes signify therapeutic interventions, such as treatments. Blue boxes signify investigations, such as endoscopy, or disease status, such as remission. If you have ideas on how to improve the visualization, please let us know.

When do you plan to add more algorithms?

Crohn's Disease & Ulcerative Colitis algorithms are currently available. We also plan to add additional resources and information in the coming months.

Who developed the e-Guide?

The development of the e-Guide was led by Dr Marcus Harbord. The full list of contributors can be found on the About page.
The e-Guide web platform was developed by Sociable Data, who support the e-CCO e-Guide by means of an educational grant.
