Instructions for Authors

RAD is an international peer-reviewed medical journal open to physicians and scientists from the field of biomedicine. It accepts contributions in the form of original article, review, short review, case report, letter to the editor, short communication, and correspondence. 

Plagiarism detection

Manuscripts are checked for text similarity and manually verified by the research integrity editor. We use CrossRef Similarity Check software (https://www.crossref.org/services/similarity‐check/) and deal with manuscripts suspected on plagiarism following the COPE flowcharts (http://publicationethics.org/resources/flowcharts) and ICMJE guidelines.

Ethical approval and informed consent

When reporting trials on human subjects, authors should indicate whether the procedures were in accordance with the ethical standards set by the responsible human experimentation committee (institutional and national) and latest version of the Declaration of Helsinki given by World Medical Association (link). Ethical approval (institutional or national) should be obtained for every study that includes collection of additional patient sample of any biological material (more than those required for the medical evaluation).

All subjects should sign an informed consent form and this information should be provided in the manuscript. Signed informed consent forms should be archived by the authors. The authors have to provide a statement that they have received and archived all patient informed consent forms, as required during the manuscript submission process. It should be noted that informed consent to participate in the research does not imply consent to publish personal individual data (names, pictures, hospital identification). Therefore, for publication that includes any individual data, patient must give his written consent. This is especially applied when it is not possible to obtain anonymity of the data without distorting scientific evidence.

Regardless of the preserved anonymity, patients presented in case report articles should always sign informed consent. Case reports without patients’ consent are not eligible for publication in Rad.

Language

Rad  is published exclusively in english. It is the author’s responsibility to ensure that the English language is thoroughly revised before submitting the work for publication. Note that the Editorial Office reserves the right to reject a manuscript if the use of language is deemed too poor.

Article processing charges

Manuscript submission, article processing and publishing is free of charge.

Autorship

Rad follows the guidelines for authorship set forth by the International Committee of Medical Journal Editors (ICMJE) (available at: http://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html).

Each author should meet all four criteria as follows:

  1. substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data
  2. drafting the article or revising it critically for important intellectual content
  3. final approval of the version to be published
  4. agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

According to ICMJE: “In addition to being accountable for the parts of the work the author has done, an author should be able to identify which co-authors are responsible for specific other parts of the work. In addition, authors should have confidence in the integrity of the contributions of their co-authors. All those designated as authors, should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors.“

Rad adopted the system by which each author is identified with his/her unique identification number, ORCID, thus ensuring transparency in authorship and personal identification. It is available for free at http://orcid.org/. It is recommended for each author to provide his/her ORCID number.

Manuscript submission

During the manuscript submission process corresponding author is asked to provide his ORCID ID number. Corresponding author is responsible to fill in the Submission formon behalf of all co-authors. Manuscript Submission formconsists of following sections: authorship statement, statement of originality, conflict of interest disclosure, protection of research participants, and copyright transfer and publication license.

Instructions for authors comply with the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals” (http://www.icmje.org/recommendations/, updated in 2016). Editors hold the right to make all the necessary changes to the language and style of the original manuscript in order to adhere to the uniform standards of the Journal.

Manuscript preparation

Please note that the cover letter and title page are not included into the manuscript file.

All pages of the manuscript (except for the cover letter and title page, which are attached separately) should be within a single document. Original manuscripts should be structured as follows: Abstract, Keywords, Introduction, Materials and Methods, Results, Discussion, Acknowledgments, Tables and Figures, and References.

Abstract

All types of manuscripts should contain an abstract. An abstract of 250 words maximum should be provided on a separate page in the Manuscript file (abstract only, without authors and affiliation). The abstract of an original article should be structured into four headings: IntroductionMaterials and MethodsResults,and Conclusions. For other article types, abstracts do not have to be structured.

Keywords

Please whenever possible, provide 3-5 keywords from MeSH database, available at http://www.nlm.nih.gov/mesh/meshhome.html

Introduction

In the Introductionsection, the authors should point out new information in the manuscript, the hypothesis, and the aim of their work. The Introduction section should not contain results and conclusions.

Materials and methods

The Materials and methodssection should only include information that was available at the time the study was planned. All information obtained during the study should be provided in the Resultssection. This section should be structured as follows:

  • Subjects (if research includes human subjects), 
  • Materials(otherwise);
  • Methods
  • Statistical analysis.

In the Subjects/Materialssection it is recommended to include the following:

  • time and place of the study (the dates of the beginning and the end of the study);
  • study design (case-control, cohort, diagnostic accuracy etc.);
  • inclusion and exclusion criteria;
  • relevant demographic and history details (age, gender, diagnostic criteria etc.);
  • ethical approval and informed consent. 

In the Methodssection, methods, instruments (give the manufacturer’s name, town and country in parentheses), and procedures should be described in sufficient detail to allow other researchers to reproduce the results. For well-established methods, only references should be provided.

Example: All tests were run on Roche Cobas C501 chemistry analyzer (Roche Diagnostics GmbH, Mannheim, Germany).

In the Statistical analysissection, authors should list all statistical methods used in the study and preselected level of significance (P). If possible, findings should be quantified and presented using appropriate indicators of measurement error or uncertainty (e.g., confidence intervals).

At the end of this section, authors should specify the statistical software used.

Results 

State the main or most important finding first. The data presented in the tables or figures should not be repeated in the text. Graphs should be used as an alternative to tables with many entries; do not present the same data in duplicate (e.g., in both graphs and tables). Exact P-values should be provided for all tested differences (e.g., write P=0.044 instead of P<0.05) rounded to three decimal places.

Discussion

Emphasize the new and important conclusion based on the study results in the context of the best available evidence. Do not repeat the data presented in the Introductionor Resultssection. Clearly state the limitations of the study.

Acknowledgments

All contributors who do not meet the authorship criteria should be listed in the Acknowledgmentssection. These persons must give verbal permission to be acknowledged. Authors should provide that statement during the manuscript submission process. Financial and material support should also be acknowledged and reported in conflict of interest disclosure during the manuscript submission process.

References

Authors are responsible for verifying the accuracy of the references by using an electronic bibliographic source, such as PubMed, or printed original articles. References must not refer to the retracted article except if the authors want to refer to the particular retraction.

Radapplies Vancouver referencing style. Literature citation should conform to the standards available at NLM’s International Committee of Medical Journal Editors (ICMJE) Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals: Sample References available at http://www.nlm.nih.gov/bsd/uniform_requirements.html. References should be numbered consecutively, using Arabic numerals in parentheses, in the order of appearance in the text.

For example:
Prostatic carcinomas with the final score <7 were considered low-intermediate grade; and, with the final score >7 were considered high-grade (4).

References cited only in tables or figures should be numbered in accordance with the sequence established by the first appearance in the text of the table or figure. Also, the authors should notinclude DOI numbers at the end of cited reference.

Journal titles should be abbreviated according to the style used in the NLM Catalog: Journals referenced in the NCBI Databases, posted by the NLM and available at: http://www.ncbi.nlm.nih.gov/nlmcatalog/journals.

The most common examples are as follows:

Journals:

Name all authors unless there are more than seven, in which case list the first six plus et al.

Conflict of interest
According to the International Committee of Medical Journal Editors (ICMJE): “Conflict of interest exists when an author (or the author’s institution) has financial (employment, consultancies, stock ownership, honoraria and paid expert testimony) or personal relationship, academic competition or intellectual passion that inappropriately influences his actions.” (available at: http://www.icmje.org/recommendations/browse/roles-and-responsibilities/author-responsibilities–conflicts-of-interest.html)

Other possible conflict of interest
All reviewers, editors, section editors, Editorial Board members, included in the publication process will also be asked to disclose any potential conflict of interest regarding the manuscript they are asked to review (primarily relationships with the pharmaceutical industry; incorporated into our submission system).
