Authorship: Contributions Disclosure for All Authors as Stated by Corresponding Author or by Individual Authors

Objective: To analyze authors' contributions described by the corresponding author and individual authors in the Croatian Medical Journal (CMJ) and satisfaction of authorship criteria of the International Committee of Medical Journal Editors (ICMJE). Method: We analyzed contributions of all authors of a research paper as stated by the corresponding author or by each individual author listed in the byline. The sample comprised 201 research articles with two or more authors submitted to the CMJ from 2001 to 2002, representing 919 authors. The authors chose their contributions from the list of 11 categories, six of which were not related to ICMJE authorship criteria. Authorship was defined as true if all three ICMJE criteria were met, partial if any of the criteria was met, and false if none of the criteria were met. Findings: Out of 718 non-corresponding authors, 201 (28.0%) fully met the ICMJE criteria for authorship according to the statement given by the corresponding author. When they themselves described their own contributions, this prevalence increased to 40.0% (difference 12% ; 95% confidence interval (CI) 15.2 to 8.7%). Significant difference (u kojem smjeru? koji je je veci ili manji?)was found in the contribution disclosure of the corresponding or individual authors for partial authorship (difference 8.5% ; 95% CI 4.7 to 12.3%). Prevalence of false authors was lower according to individual authorship statements than to corresponding author statement (difference 3.5% ; 95% CI 1.4 to 5.7%). ( a što je s onim da corresponding autori nisu jednako zabiljezili svoje contributions kad su odgovarali na dva nacina!?) Conclusions: Authorship statements provided by corresponding authors only may not be a true reflection of authors' contributions to the research described in a published article.
