To the Editor: Constraints on the publication rights of clinical investigators in industry-initiated trials have been described,1,2 but have been investigated in surveys that relied mainly on individuals' recall and attitudes and may have underestimated the extent of its occurrence. We examined directly the presence of constraints in trial protocols and subsequent publications.
