Somehow one of the 3 experimental groups has 16 people, whereas the other groups have 14 people. Wonder why...

For what is worth studies do end up with different amounts of people due to dropping out, people not matching criteria which are only checked later, indivisibility by number of groups etc.

Yes, there are legit reasons for this to happen, as well as cherry-picking.
