When I read studies, the intention-to-treat aspect is usually mentioned, and compliance statistics are usually given, but it’s usually communicated in a way that lays traps for people who aren’t reading carefully. Ie, if someone is trying to predict whether the treatment will work for their own three year old, and accurately predicts similar compliance issues, they’re likely to arrive at an efficacy estimate which double-discounts due to noncompliance. And similarly when studies have surprisingly-low compliance, people who expect themselves to comply fully will tend to get an unduly pessimistic estimate of what will happen.
