Lacasse JR, Leo J. Knowledge of ghostwriting anf financial conflicts-of-interest reduces the perceived credibility of biomedical research. BMC Research Notes 2011;4:27
This study provides information on how practicing clinicians perceive research in which multiple conflicts of interest (COI) are disclosed. The authors developed two research vignettes presenting a fictional antidepressant medication study, one in which the authors had no COI and another in which there were multiple COI disclosed. Perceived credibility ratings were much lower in the COI group that is, increased disclosure of COI resulted in lower credibility ratings.
