Conflicts of interest and recommendations in clinical guidelines, opinion pieces, and narrative reviews (Protocol)

Abstract

This is a protocol for a Cochrane Review (Methodology). The objectives are as follows: We will investigate whether: • Clinical guidelines written by authors with financial or non-financial conflicts of interest are more likely to recommend an intervention; • Opinion pieces written by authors with financial or non-financial conflicts of interest are more likely to recommend an intervention; • Narrative reviews written by authors with financial or non-financial conflicts of interest are more likely to recommend an intervention.
