Having collected data, it can be tempting to publish several articles on the same dataset. However, there is a difference between publishing articles with clear overlap, and distinct studies. In short, when the overlap is sufficient so that the studies could have been combined for a more impact article, it is not good. It distorts the literature and wastes the time of the reader, reviewers and editors.

Data overlap is acceptable in the case where: There are different and distinct questions with multiple and unrelated endpoints; and /or the data collection is large or drawn out that it is impractical to publish all simultaneously and other researchers would benefit from earlier publications.
