The consensus is actually an international document that is produced by experts around the world following the two-day symposium. They give a consensus on the evidence that is presented.
For example, in the last 2016 Berlin consensus, over 64,000 articles were reviewed, and from that, then, there is a consensus, which is based on scientific evidence.
Those guidelines are so related to scientific evidence they provide the current status of what we know in concussion. They really form the basis of other groups, such as Parachute and Hockey Canada, giving their guidelines, because they will usually follow the consensus, which becomes what I would say is the leading document in the field so that different groups can then look at it and adopt it, or adopt some parts of it.
