In addition to the manuscript files, authors are required to submit the following during the initial submission:

Preparation of the Manuscript

Title page: A separate title page should be submitted with all submissions and this page should include:

  • The full title of the manuscript as well as a short title (running head) of no more than 50 characters,
  • Name(s), affiliations, highest academic degree(s), and ORCID IDs of the author(s),
  • Grant information and detailed information on the other sources of support,
  • Name, address, telephone (including the mobile phone number), and email address of the corresponding author,
  • Acknowledgment of the individuals who contributed to the preparation of the manuscript but who do not fulfill the authorship criteria.
  • If the author(s) is a member of the journal’s Editorial Board, this should be specified in the title page.

Abstract: An abstract should be submitted with all submissions except for Letters to the Editor. The abstract of Research Articles should be structured with subheadings (Objective, Methods, Results, and Conclusion).

Keywords: Each submission must be accompanied by a minimum of three to a maximum of six keywords for subject indexing at the end of the abstract. The keywords should be listed in full without abbreviations. The keywords should be selected from the National Library of Medicine, Medical Subject Headings database (https://www.nlm.nih.gov/mesh/MBrowser.html).

Main Points: All submissions except letters to the editor should be accompanied by 3 to 5 “main points.” These main points should highlight the most important results of the study and emphasize the main message of the manuscript. The main points should be structured as a list and should be written in a clear and straightforward manner. Since the main points are intended for experts and specialists in the field, they should be written in plain language that is easy to understand. By including main points with the manuscript, authors can help ensure that the most important findings and messages of their study are conveyed clearly to the reader.

Manuscript Types

Research Articles

Research articles provide new information based on original research. The acceptance of research articles is typically based on the originality and importance of the research. The main text of a Research Article should be structured with subheadings, including Introduction, Material and Methods, Results, and Discussion.

Clinical Trials

Clinical Science of Nutrition adopts the ICMJE's clinical trial registration policy, which requires that clinical trials must be registered in a publicly accessible registry that is a primary register of the WHO International Trials Registry Platform (ICTRP) or in ClinicalTrials.gov. By registering clinical trials in a publicly accessible registry, authors can help to promote transparency and accountability in their research.

Instructions for the clinical trials are listed below.

  • Clinical trial registry is only required for the prospective research projects that study the relationship between a health-related intervention and an outcome by assigning people to different groups.
  • To have their manuscript evaluated in the journal, authors should register their research to a public registry at or before the time of first patient enrollment.
  • Based on most up to date ICMJE recommendations, Clinical Science of Nutrition accepts public registries that include minimum acceptable 24-item trial registration dataset.
  • Authors are required to state a data sharing plan for the clinical trial registration. Please see details under the “Data Sharing” section.
  • For further details, please check ICMJE Clinical Trial Policy and COPE Data and Reproducibility guidelines.

Reporting Statistical Analysis

Statistical analysis to support conclusions is usually necessary. Statistical analyses must be conducted in accordance with international statistical reporting standards (Altman DG, Gore SM, Gardner MJ, Pocock SJ. Statistical guidelines for contributors to medical journals. Br Med J 1983: 7; 1489-93). Information on statistical analyses should be provided with a separate subheading under the Materials and Methods section and the statistical software that was used during the process must be specified.

When reporting statistical data in a research paper, it is important to present the values in a clear and consistent manner. P values, confidence intervals (CIs), and other statistical measures should be rounded appropriately and expressed according to the guidelines provided. For example, P values should be expressed to two digits to the right of the decimal point unless the first two digits are zeros, in which case three digits should be provided (eg, instead of P < .01, report as P = .002). However, values close to .05 may be reported to three decimal places because .05 is an arbitrary cut-off point for statistical significance (eg, P = .053). P values less than .001 should be designated as P < .001 rather than providing the exact value (eg, P = .000006).

Units should be prepared in accordance with the International System of Units (SI).

Review Articles

Review articles that are written by authors with extensive knowledge and expertise in a particular field and a strong track record of publication are welcomed. These authors may even be invited to contribute a review article to the journal. Review articles should provide a comprehensive overview of the current state of knowledge on a topic in clinical practice, and should include discussions and evaluations of relevant research. The subheadings of the review articles can be planned by the authors.

Case Reports

The journal has limited space for case reports, and prioritizes publishing reports on rare cases or challenging conditions that provide new insights into diagnosis and treatment, offer novel therapies, or reveal knowledge not yet included in the literature. Interesting and educational case reports are also welcomed for publication. The text of a case report should include Introduction, Case Presentation, and Discussion sections. An unstructured abstract should also be included.

Letters to the Editor

A "Letter to the Editor" is a type of manuscript that discusses important or overlooked aspects of a previously published article. This type of manuscript may also present articles on subjects within the scope of the journal that are of interest to readers, particularly educational cases. Readers can also use the "Letter to the Editor" format to share their comments on published manuscripts. The text of a "Letter to the Editor" should be unstructured and should not include an abstract, keywords, tables, figures, images, or other media. The manuscript that is being commented on must be properly cited within the "Letter to the Editor."

Editorial Comments

Invited brief editorial comments on selected articles are published in the CClinical Science of Nutrition. Editorials should not be longer than 1000 words excluding references. Editorial comments aim to provide a brief critical commentary by reviewers with expertise or with high reputation in the topic of the research article published in the journal. Authors are selected and invited by the journal to provide such comments. Abstract, Keywords, and Tables, Figures, Images, and other media are not included.

Tables

Tables should be included in the main document, after the reference list, and they should be numbered consecutively in the order they are referred to within the text. Each table should have a descriptive title placed above it, and any abbreviations used in the table should be defined below the table by footnotes (even if they are defined in the main text). Tables should be created using the "insert table" command of the Word processing software, and they should be arranged clearly to make the data easy to read and understand. The data presented in the tables should not be a repetition of the data presented in the main text, but should support and enhance the main text.

Figures and Figure Legends

Figures should be submitted as separate files in TIFF or JPEG format, and they should not be embedded in the Word document or the main manuscript file. If a figure has subunits, each subunit should be submitted as a separate file, and the subunits should not be merged into a single image. The figures should not be labeled (a, b, c, etc.) to indicate subunits. Instead, the figure legend should be used to describe the different parts of the figure. Thick and thin arrows, arrowheads, stars, asterisks, and similar marks can be used on the images to support figure legends.Images should be anonymized to remove any information that may identify individuals or institutions. The minimum resolution of each figure should be 300 DPI, and the figures should be clear and easy to read. Figure legends should be listed at the end of the main document. Figures should be referred to within the main text, and they should be numbered consecutively in the order in which they are mentioned.

Abbreviations

All acronyms and abbreviations used in the manuscript should be defined at first use, both in the abstract and in the main text. The abbreviation should be provided in parentheses following the definition, and it should be used consistently throughout the paper.

Identifying products

When mentioning a drug, product, hardware, or software program in a manuscript, it is important to provide detailed information about the product in parentheses. This should include the name of the product, the producer of the product, and the city and country of the company. For example, if mentioning a Discovery St PET/CT scanner produced by General Electric in Milwaukee, Wisconsin, USA, the information should be presented in the following format: "Discovery St PET/CT scanner (General Electric, Milwaukee, WI, USA)." Providing this information helps to ensure that the product is properly identified and credited.

Supplementary Materials

Supplementary materials, including audio files, videos, datasets, and additional documents (e.g., appendices, additional figures, tables), are intended to complement the main text of the manuscript. These supplementary materials should be submitted as a separate section after the references list. Concise descriptions of each supplementary material should be included to explain their relevance to the manuscript. Page numbers are not required for supplementary materials.

References

Both in-text citations and the references must be prepared according to the AMA Manual of Style 11th Edition.

When citing publications, preference should be given to the latest, most up-to-date sources. Citing the latest sources can help to ensure that the paper is relevant and timely, and that it reflects the latest developments in the field.

It is the responsibility of the authors to ensure the accuracy of the references in their article. All sources must be properly cited, and the citations must be formatted correctly.

In the main text of the manuscript, references should be cited in superscript after punctuation.

If an ahead-of-print publication is cited, the DOI number should be provided in the reference list.

Journal titles should be abbreviated in the reference list in accordance with the journal abbreviations in Index Medicus/MEDLINE/PubMed.

When there are six or fewer authors, all authors should be listed. If there are seven or more authors, the first three authors should be listed followed by “et al.” in the reference list.

Production

Once a manuscript has been accepted for publication, it goes through a copy-editing process by professional language editors to ensure that it is clear and well-written. This process may involve correcting grammar, punctuation, and formatting errors, as well as making changes to improve the overall clarity and readability of the manuscript.

After the copy-editing process is complete, the manuscript is published online as an "ahead-of-print" publication, which means that it is available to readers before it is included in a scheduled issue of the journal. This allows readers to access the latest research as soon as it becomes available.

Before the manuscript is officially published, the corresponding author is sent a PDF proof of the accepted manuscript for review. The corresponding author is asked to review the proof and approve it for publication within a specified time period, typically 2 days. This is an important step in the publication process, as it allows the author to catch any errors or make any final changes before the manuscript is published.
