Further information can be provided in the contributorship statement if necessary.
When submitting a manuscript authored by a group, the corresponding author should specify the group name if one exists, and clearly identify the group members who can take credit and responsibility for the work as authors.
Contributorship statement A contributorship statement is required for every manuscript submitted and should outline who has contributed what to the planning, conduct, and reporting of the work described in the article.
The individuals who conduct the work are responsible for identifying who meets these criteria and ideally should do so when planning the work, making modifications as appropriate as the work progresses.
Each author should be able to identify which co-authors are responsible for specific other parts of the work.
It also rules out authorship solely by virtue of being the PI of the lab in which the other authors worked.
The byline of the article identifies who is directly responsible for the manuscript, and MEDLINE lists as authors whichever names appear on the byline. Because authorship does not communicate what contributions qualified an individual to be an author, some journals now request and publish information about the contributions of each person named as having participated in a submitted study, at least for original research.
For instance, respondents who said making extensive comments on a draft ms is sufficient for authorship were not a strict subset of those who said providing lots of data originally collected for another purpose is sufficient for authorship.
