Does declaration of competing interests affect readers' perceptions? A randomised trial

摘要

Conflict of interest has been defined as a set of conditions in which professional judgment concerning a primary interest (such as patient welfare or the validity of research) can be influenced by a secondary interest (such as financial gain). Despite increasing evidence that conflict of interest influences authors' conclusions, we found no research into the effect on readers' perceptions of research. We studied whether a declaration of financial competing interest influences reader's perceptions of the interest, importance, relevance, validity, and believability of a study.
