Conflicts of interest should be as transparent as the disclosures of standardized authors. Financial and personal relationships are easily identifiable, which may lead to bias or bias in the work. The sources of funding for the work should be specifically described with explanations of the role of those sources, and the authors should state that the sources of support did not have a specific role to play. The authors should state that the authors have access to all the studies and that the sponsors have not intervened in the data or work. If there is none, the authors can state, "The authors declare no conflict of interest".
