A study by von Elm et al3 revealed that there are 6 distinct patterns of duplication and that authorship was an unreliable criterion for discovery. Also, duplicates were published in similar-type journals, and citations to the duplicates were as frequent as the main articles.3 That practice might be considered by some as a variation on the time-honored academic model of team effort toward promotion in rank by using various studies to answer one scientific question. However, duplicate publication is dishonorable—in whatever way it is couched.
