Original research articles 

Original articles report on data from experimental studies. The manuscripts should contain an introduction, materials and methods, results, and discussion section. Authors are allowed to combine the results and discussion section. 


Review articles may encompass all types of reviews as described by Grant and Booth in Health Info Libr J 2009;26:91-108 A summary of the types of reviews as described in the Grant and Booth paper can be downloaded here.

Technical reports

Technical reports present a new experimental model, method, treatment or intervention, test procedure, or tool that is relevant for clinical and translational research, diagnostics/prognostics, or analysis of data sets. Reports on clinical trial setup and management as well as experimental design are also acceptable, as long as these contain non-normative information and add value to the standard protocol.

Medical hypotheses

Medical hypothesis articles provide authors with the freedom to speculate about everything related to human disease and the alleviation thereof. The aim of these articles is that a conceptual framework is provided for medical phenomena or novel (potential) technologies. Ideally, the conceptual framework should spawn new research, so it is recommended that current bottlenecks and future directions are explicitly addressed. Examples include biochemical or physiological pathways that may explain the elusive pathogenesis of a disease, description of novel technologies, including those that are patented, that have not yet been clinically tested, epidemiological prediction models, etc. Authors may also theorize on inexplicable findings in their own studies or those published by others. All conjecture must be supported by valid premises that in turn are backed up by (ancillary) data, either derived from literature or from focused experiments. Medical hypothesis articles should provide thorough insights and abide by all facets of critical reasoning and logic. Because of their nature, the articles will typically undergo a more stringent review process than the other types of articles.

Special issue articles 

Special issues are a collection of timely, high-quality articles on a particular topic that are published together in an extraordinary single issue of the journal under the auspices of guest editors. Interested guest editors should Link - contact the editor-in-chief regarding the hosting of a special issue. Special issue articles will undergo regular peer review.


Editorials are peer-reviewed contributions from editorial board members.

Articles from non-English language journals

Science is advanced by publications that educate and expand our knowledge. Such publications have a maximum effect when they reach a wide audience. In order to facilitate this process, JCTR will publish the English version of high-quality articles that have been published in a non-English language journal. Publication of non-English journal articles will only proceed on the condition that no copyright laws are violated. JCTR has a multi-lingual editorial board (including Chinese, Indonesian, Dutch, Czech, and French) and offers translation services to interested authors. Please Link - contact the managing editor for more information.

Commissioned articles

Commissioned articles are timely articles on niche-transcending, broadly applicable themes in clinical and translational research, often written against a backdrop of current developments and events. Editors will work with the authors on the framework and content of the article. Typically, proponents as well as adversaries of the topic will make up the team of authors to ensure a balanced, multi-perspective view on the subject matter. Authors should contact the editor-in-chief about their interest in contributing a commissioned article and provide a tentative outline and list of co-authors. Commissioned articles will undergo regular peer review.
