Instructions for Authors


New toolbox for authors

We have prepared a useful tool for the authors of our journal, including guidelines needed while working on a new article. We hope that provided instruction will address any of your concerns. Before uploading a new manuscript, read Stylebook in a Nutshell and get acquainted with all necessary information.

Please read thorougly and familiarize yourself with our new statistical guidelines.

The Editorial Board accepts manuscripts for publication written in US English. They may be considered for publication in the following sections:

  • Original papers – including experimental research;
  • Systematic Reviews;
  • Meta-Analyses; 
  • Research-in-Progress;
  • Editorials; 
  • Research letters. 

Advances in Clinical and Experimental Medicine DOES NOT ACCEPT case reports. Priority will be given to original papers developed as part of international cooperation.

The Editorial Office reserves the right to change the category of the manuscripts if its contents require it – e.g., from Original Paper into Meta-analysis or Research letter.

The submitted manuscripts should meet the general standards and requirements agreed upon by the International Committee of Medical Journal Editors, known as “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals”. They should also conform to the high-quality editorial procedures and practice (formulated by the Index Copernicus International Scientific Committee as Consensus Statement on Good Editorial Practice 2004).

If the article is already accessible online as registered preprint on any website or in any database, and has been already assigned with a DOI, such information, together with an URL of the registered preprint, has to appear in the cover letter.

Submission of manuscripts

All manuscripts should be submitted to Editorial Office via electronic Editorial System. Tables and figures should be submitted separately; linked files such as images or charts should also be provided. WE DO NOT ACCEPT manuscripts sent by post or e-mail.


The authorship should be based on the following criteria:

  • Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work;
  • Drafting the work or revising it critically for important intellectual content;
  • Final approval of the version to be published.

Authors should meet all three (3) above criteria. If a large, multi-center group conducted the research, the group should identify the individuals who accept direct responsibility for the manuscript. The Author submitting a collectively authored manuscript should establish the order of authorship, provide all individual authors of the particular group, as well as provide the group's name. All those designated as authors should meet all criteria for authorship, and all who meet the criteria should be identified as authors. The contribution of each Author must be documented to the extent to take the public responsibility for appropriate portions, the content and the conflict of interests. Authors who do not meet all three criteria of authorship should be acknowledged (prior to their written consent).

All Authors who have made significant contributions should be listed as co-authors and their authorship should be disclosed in accordance with the following list:

A – research concept and design; B – collection and/or assembly of data; C – data analysis and interpretation; D – writing the article; E – critical revision of the article; F – final approval of article.

Ghostwriting and guest authorship are manifestations of scientific misconduct, and any detected cases will be unmasked, including notification of the relevant entities (institutions employing the authors, scientific societies, associations, scientific editors, etc.). Editors require the identification of funding sources of publications, information about contribution to research from institutions, associations and other entities (the rule: financial disclosure). Editors continuously monitor and document any signs of scientific misconduct, especially violations and breaches of ethics applicable in the study.

Changes to authorship
Before manuscript submission, provide the final and definite list of all authors. If you want to add, remove or change the order of the authors, you can do it only before the manuscript acceptance. Each change, however, should be always approved by the journal Editor.

To make authorship changes, send to the Editorial Office:

1. the reason for the change in the author list; and

2. a written signed consent (via e-mail/letter) from all authors stating that they agree with the addition, removal or rearrangement in the list.

We require such signatures from all authors, even those who have been added or removed. In exceptional circumstances our Editors can consider the addition, deletion or rearrangement of authors after the manuscript acceptance. Please note, however, that the process of publication will be suspended until Editors reach such a decision.

Changes of authorship following the acceptance of the manuscript for publications are not permitted.

Preparation of manuscripts

Articles must be written in US English. Authors not entirely familiar with English usage are advised to seek the assistance of an English speaker; correct style is the responsibility of the authors. The journal does not offer translation services.


Manuscripts which are not adequately prepared will be returned to the corresponding Author and rejected if we do not receive proper revisions within 30 days. 


Abstract of ORIGINAL PAPERS, META-ANALYSES and RESEARCH LETTERS should contain from 200 to 300 words and should consist of 5 separate parts introduced by separate subheadings in the following order:

  • Background
  • Objectives
  • Materials and methods
  • Results
  • Conclusions.

An unstructured abstract of 150 to 250 words is required for REVIEWS.

All abbreviations used in the text should be explained in the article.

Graphical abstract

The journal Advances in Clinical and Experimental Medicine accepts also additional visual abstracts (also known as graphical abstracts) as a complement for text abstracts. Such abstract is a single, concise, pictorial and visual summary of the main findings of the article. It should be a figure that is specially designed for the purpose, which captures the content of the article for readers at a single glance. Authors must provide an original image that clearly represents the work described in the paper. Graphical abstracts should be submitted as a separate file in the submission system as Figure 0. For ease of browsing, the graphical abstract should have a clear start and end, preferably "reading" from top to bottom or left to right. Try to reduce distracting and cluttering elements as much as possible. No additional text, outline or synopsis should be included. Any text or label must be part of the image file. Please do not use unnecessary white space or a heading “graphical abstract” within the image file. Allowed data formats: for VECTOR graphics (charts, diagrams, etc.) - pdf, eps, ai, cdr (if the graphic was created using MS Office programs, source files of a given program are very helpful: doc, docx, ppt, pptx, xls, xlsx); for BITMAP graphics (photos, screenshots) - tif, jpg, png, bmp (min. 1000 pixels of the base in the drawing with the width of one column and 2100 for the width of two columns). The minimal resolution of tif, jpg and png files is 300 dpi.

More on how to prepare visual abstract (with examples):

Key words

Abstract should be followed by 3–5 key words written in the language of the manuscript and recommended by the Index Medicus Subject Headings (MeSH).

Main text

Manuscripts should be submitted in the following formats: doc, docx, rtf.

The total number of words in SYSTEMATIC REVIEWS and META-ANALYSES should not exceed 7,000 words (including main text, tables and figure legends, and excluding reference list), 3,500 words in ORIGINAL PAPERS (including main text and figure legends, but excluding title page, abstract and references) and 1,500 words in RESEARCH LETTERS.

We accept up to 6 tables/figures (2 figures and 2 tables in Research letters).

References to literature, figures and tables should be placed in the order of their citation in the text. The Author(s) should not use italics, bold or underlined words in the texts. Please use only generic names of drugs.  Laboratory values should be expressed using the International System of Units (SI). The Author(s) should provide a short title that does not exceed 45 characters and spaces. The Author(s) should disclose all financial and material support.

In addition, when preparing the manuscript, it is obligatory to consider the structure of the article according to one of the checklists below:

It is obligatory to refer to the EQUATOR site as a reference in selecting the appropriate checklist for the study: The checklist needs to be uploaded in the Editorial System separately.

Units of measure

Laboratory values should be expressed using the International System of Units (Le Système International d’Unités, SI). Temperatures are to be given in degrees Celsius. If conventional units are used, their SI equivalents should be provided in parentheses only at first mention in the text.


Abbreviations should not be used unless they appear at least 3 times in the text. Nonstandard abbreviations should be avoided. Do not use abbreviations in manuscript titles (except when space considerations require otherwise) or figure legends and table titles. In rare cases, when the abbreviation is more familiar than the expansion, the abbreviation alone can be used (e.g. DNA). Abbreviations without expansion can also be used for statistical terms listed in the Statistical analysis section below.


Tables should be placed in separate files. References to Tables should be placed according to the sequence of citing them in the manuscript. Allowed formats: xls, xlsx, doc, docx.


Figures should be placed in separate files. References to Figures should be placed according to the sequence of citing them in the manuscript. Allowed data formats: for VECTOR graphics (charts, diagrams, etc.) - pdf, eps, ai, cdr (if the graphic was created using MS Office programs, source files of a given program are very helpful: doc, docx, ppt, pptx, xls, xlsx); for BITMAP graphics (photos, screenshots) - tif, jpg, png, bmp (min. 1000 pixels of the base in the drawing with the width of one column and 2100 for the width of two columns). The minimal resolution of TIFF, JPG and PNG files is 300 dpi.

If Authors used in the Work any figures, photographs, charts, tables, etc. which are not their work, and are protected by the copyright law, they shall be obliged to provide the Publisher with a written authorization to use such materials issued by the author’s economic rights holders. The Author is required to provide the source of all figures, photographs, charts, etc.

The maximal number of figures for a RESEARCH LETTER is 3. This is the maximal number of single chart/graphs/photographs; a panel containing of, e.g., 4 elements and numbered as Fig. 1 counts as 4 figures, not 1.


It is the responsibility of the authors to ensure the accuracy of all references according to AMA citation style. References should be limited only to the most recent positions and directly connected to the presented topic. References should be identified by Arabic numerals in superscript and numbered consecutively in the order in which they are first mentioned in the manuscript. Abbreviations for journal names should be cited according to Index Medicus. If a journal is not listed in Index Medicus, its full name should be given. If the cited work is available online, the DOI number should be given, and in the case of lack thereof - URL with the access date.  Reference to articles that are accepted for publication may be cited as "in press", whereas manuscripts that are still in preparation or submitted for publication should be referred to as "unpublished data". This journal should be cited in lists as Adv Clin Exp Med.


                                                                      Please provide DOI for all cited works. 

Anonymous review

All manuscripts will be subject to a process of anonymous editorial review (the name of authors and their affiliations will be disclosed to the reviewers only when the review process is complete). In order to achieve this, the first page and the acknowledgements page will be removed from the manuscripts sent to reviewers. Manuscripts will be sent to at least 2 independent reviewers. The final decision on accepting the manuscript is made by the Editorial Board, reviews are only supporting this decision. The Editorial Board’s final evaluation of each article is based on criteria developed by the Committee on Publication Ethics (COPE).


Authors should keep a copy of their article, as proofs will be sent to them without the manuscript. Corrections to the proofs should be restricted to printer’s errors only. In order to maintain rapid publication, proofs should be returned via Editorial System within 48 hours after receipt. If the Publisher receives no response from the authors after 48 hours, the manuscript will not be published.

Please note that since October 1, 2021 after the article is published as ahead of print, it cannot be changed (which encompasses also affiliations and authors’ order). Such stipulation stems from requirements set by scientific databases in which the papers published in Advances in Clinical and Experimental Medicine are stored.
