Articles should be published with statements or supporting documents, such as the ICMJE conflict of interest form, declaring:
•    Authors’ conflicts of interest; and
•    Sources of support for the work, including sponsor names along with explanations of the role of those sources if any in study design; collection, analysis, and interpretation of data; writing of the report; the decision to submit the report for publication; or a statement declaring that the supporting source had no such involvement; and
•    Whether the authors had access to the study data, with an explanation of the nature and extent of access, including whether access is on-going.
To support the above statements, editors may request that authors of a study sponsored by a funder with a proprietary or financial interest in the outcome sign a statement, such as “I had full access to all of the data in this study and I take complete responsibility for the integrity of the data and the accuracy of the data analysis.”
