3. Introduction

Redundant Publication:
It is publishing essentially the same manuscript more then once, with perhaps
a few changes in the wording or emphasis. Publishing multiple reports from
a single very large project may be justified when each report addresses an
important and distinct question and data do not overlap despite the fact that
there may be authors and patients in common. (Angell and Relman 1989)

4. Introduction

Salami slicing:
Salami publication can be roughly defined as a publication of two or more
articles derived from a single study. It describes the practice of dividing data
from a single study into several publications, especially when this is
inappropriate and done to boost the author’s publications rather than to
present the research in the clearest possible way.
Articles of such type report on data collected from a single study split into
several segments just large enough to gain reasonable results and
conclusions, also known as “minimal publishable unit”. (Supak Smolcić
2013)

Detecting redundant publication:
The manuscripts suspected of being salami publications often report on
identical or similar (von Elm, Poglia et al. 2004)

8. Case Study
8
• Transesophageal Echocardiography in the Diagnosis of Traumatic
Rupture of the Aorta (Smith, Cassidy et al. 1995)
• Notice of Redundant Publication: Transesophageal Echocardiography in
the Diagnosis of Traumatic Rupture of the Aorta. (Young, Joynt et al.
1995).
• Authors statement: “We wish to acknowledge substantial redundancy of patients in our 1995 Journal study
of 93 patients with suspected aortic injury.” Seventy-six of these patients, 8 of whom had positive results on
transesophageal echocardiography, had been included in a study of 160 patients with the same condition published in
the Journal of Trauma in 1994. The 1994 study also included many patients described one year earlier in our initial report
of the successful use of transesophageal echocardiography to diagnose thoracic aortic injury.3 Although we cited the 1993
report in our article in the Journal, we neglected to cite the larger 1994 study2 and failed to inform you that that study had
been accepted for publication. We sincerely apologize for any confusion about the total number of patients studied and any
duplication of data.

9. Steps to Avoid Duplicate Publication:
9
• Cite all related papers, including those submitted but not yet accepted;
• Keep track of copyrights to all work
• Be clear in submitting a manuscript what new information it contains;
Understand what conditions all authors listed on a manuscript endorse in
giving permission to publish a manuscript;
• Give preference to publishing a potentially “classic” and comprehensive
article instead of dissecting results into minimally publishable pieces;
• Challenge criteria for promotion that indicate greater emphasis on
quantity than quality of publications

10. Penalties
10
• If redundancy is recognized before publication, manuscripts to be
rejected.
• If redundant articles have already been published, the visible penalties are
publication of a notice of duplicate publication in both journals,
notification of the authors’ employers, and notation in indexes such as
PubMed.
• A written statement about the redundancy to be published with the notice
of duplicate publication.
• In extreme cases, the redundant articles might be retracted, even after
publication.
