Access to Data Requirement
5.5.4 Access to Data Requirement
For all reports, regardless of funding source, containing original data (research and systematic reviews), at least 1 named author should indicate that she or he “had full access to all of the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis”2-4 (see also 5.1.1, Authorship Responsibility, Authorship: Definition, Criteria, Contributions, and Requirements). This responsibility can vest with the principal investigator, the corresponding author, or the article’s guarantor. While in some research groups, particularly small ones, all authors may have access to all of the data, it is usually not meaningful to state generically that all authors had such access.
