2. Do you have any other competing interests that could pose a conflict of interest that would reasonably appear to be related to the primary interest?
Yes - Almost any provider of health care (whether publicly or privately funded) may “gain or lose" from the publication of reviews, especially when those reviews relate to surgical interventions that are provided to patients on some form of “fee for service" basis. All those organizations for which I work and provide clinical care for patients may “gain or lose" financially from publication of Cochrane Reviews.
