Undisclosed payments by pharmaceutical and medical device manufacturers to authors of endoscopy guidelines in the United States.

Background And Aims: Payments from pharmaceutical and medical device manufacturers to authors of clinical practice guidelines (CPGs) may influence practice recommendations. It is therefore important to evaluate the completeness of financial conflict of interest (FCOI) declarations among CPG authors.

Methods: We performed a cross-sectional analysis of industry payments to authors of endoscopy guidelines published by 5 GI societies between 2014 and 2017.
