Conflicts of Interest Among Authors of Systematic Reviews Regarding the Management of Chronic Non-Cancer Pain with Opioids Analgesics.

Objective: We sought to determine whether author conflict of interest (disclosed or undisclosed) or industry sponsorship influenced the favorability of reporting of systematic reviews and meta-analyses investigating the use of opioid analgesics for the management of chronic non-cancer pain.

Methods: Our search included the MEDLINE (Ovid) and Embase (Ovid) databases. Study sponsorship was determined using the funding statement provided in each systematic review.
