1. Front Matter

1.1. Title

The title of the manuscript should be concise, specific and relevant. When gene or protein names are included, the abbreviated name rather than full name should be used.

1.2 Authors and Affiliations

Authors’ full names should be listed. The initials of middle names can be provided. Institutional addresses and email addresses for all authors should be listed. At least one author should be designated as the corresponding author. As part of our efforts to improve transparency in authorship, we recommended all corresponding authors of accepted papers to provide their Open Researcher and Contributor Identifier ID (ORCID), before submitting the final version of the manuscript.

1.3 Abstract

Abstract (up to 250 words): The abstract should state briefly the purpose of the research, the principal results and major conclusions, but the presentation of experimental details should be avoided. Please do not present detailed/numbered values.

1.4 Keywords

Two to six keywords should be provided, which are specific to the article, yet reasonably common within the subject discipline.

2. Main Text

Manuscripts should be structured according to the Types of Articles (see above).

2.1 Figures and Tables

Figures and tables should appear in the body of the paper near the place where they are mentioned. High-resolution images should also be uploaded separately as figure files. The figures and tables should be cited in numeric order in the text.

All image files for figures should be labeled with the figure number (label each part if the figures include multiple parts, e.g., 2A, 2B). The figure legend should be placed below each figure and should include descriptions of each figure part and identify the meaning of any symbols or arrows. Terms used for labels and in the legend must be consistent with those in the text.

Color will be used in the journal where needed (e.g., histology slides or surgical photographs). All other figures, such as bar graphs and charts, should be submitted in black and white.

Figures for papers accepted for publication must meet the image resolution requirements. Files for line-based drawings (no grayscale) should ideally be submitted in the format they were originally created; if submitting scanned versions, files should be 1200 dots per inch (dpi). Color photos should be submitted at 600 dpi and black-and-white photos at 300 dpi.

Charts and graphs can be submitted in the original form created (e.g., Word, Excel, or PowerPoint). Photographs or scanned drawings embedded in Word or PowerPoint are not acceptable for publication.

All photographs of patients that disclose their identity must be accompanied by a signed photographic release granting permission for their likeness to be reproduced in the article. If this is not provided, the patient’s eyes must be occluded to prevent recognition.

For tables, the system accepts most common word processing formats. Tables should have a title that describes the content and purpose of the table. Tables should enhance, not duplicate, information in the text.

If you include figures that have already been published elsewhere, you must obtain permission from the copyright owner(s).

3.1 Supplementary Materials

Additional data and information can be uploaded as Supplementary Materials to accompany the manuscripts. The supplementary materials will also be available to the referees as part of the peer-review process. Any file format is acceptable, such as data sheet (Word, Excel, csv, cdx, fasta, pdf or zip files), presentation (PowerPoint, pdf or zip files), image (cdx, eps, jpeg, pdf, png or tiff), table (Word, Excel, csv or pdf), audio (mp3, wav or wma) or video (avi, divx, flv, mov, mp4, mpeg, mpg or wmv). All information should be clearly presented. Supplementary materials should be cited in the main text in numeric order (e.g., Supplementary Figure 1, Supplementary Figure 2, Supplementary Table 1, Supplementary Table 2, etc.). The style of supplementary figures or tables complies with the same requirements on figures or tables in main text. Videos and audios should be prepared in English, and limited to a size of 500 MB.

3.2 Author Contributions

Each author is expected to have made substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data; or the creation of new software used in the work; or have drafted the work or substantively revised it; AND has approved the submitted version (and version substantially edited by journal staff that involves the author’s contribution to the study); AND agrees to be personally accountable for the author’s own contributions and for ensuring that questions related to the accuracy or integrity of any part of the work, even ones in which the author was not personally involved, are appropriately investigated, resolved, and documented in the literature.

For research articles with multiple authors, a brief paragraph specifying their individual contributions must be provided. Authorship should be limited to those who have contributed substantially to the reported work. The following statements should be used “A.A.: conceptualization, methodology, software; B.B.: data curation, writing—original draft preparation; C.C.: visualization, investigation; D.D.: supervision; E.E.: software, validation; F.F.: writing—reviewing and editing. All authors have read and agreed to the published version of the manuscript.”

3.3 Funding

All sources of funding for the study should be disclosed. Clearly indicate grants that you have received in support of your research work and if you received funds to cover publication costs. Note that some funders will not refund article processing charges (APC) if the funder and grant number are not clearly and correctly identified in the paper.

Please add: “This research received no external funding” or “This research was funded by [name of funder] grant number [xxx]” and “The APC was funded by [XXX]” in this section. Check carefully that the details given are accurate and use the standard spelling of funding agency names at https://search.crossref.org/funding, any errors may affect your future funding.

3.4 Data Availability and Statistical Reporting

IJNH aims to publish both experimental and observational research. Submission of study protocols is highly recommended, alongside the statistical codes underpinning the results (ideally available in web repositories, i.e., GitHub, OSF). Results should be reported alongside measures of uncertainty (confidence or credible intervals) and emphasis given on the effect size rather than “statistical significance”. Categorizing of continuous data is not recommended. Authors should clearly state how missing data and multiple testing have been handled and the statistical section should report the software used to perform the analysis, including non-routine packages/commands. Sensitivity analyses are encouraged to assess the robustness of the results.

Authors may be asked to provide the raw data of their study together with the manuscript for editorial review and should be prepared to make the data publicly available if practicable. In any event, authors should ensure accessibility of such data to other competent professionals for at least 10 years after publication (preferably via an institutional or subject-based data repository or other data center), provided that the confidentiality of the participants can be protected and legal rights concerning proprietary data do not preclude their release.

3.5 Acknowledgements (if any)

In this section, you can acknowledge any support not covered by the author’s contribution or funding sections. This may include administrative and technical assistance or in-kind donations, such as materials used for experiments. Authors should obtain permission to acknowledge from all those mentioned in the Acknowledgments section.

3.6 Conflict of Interest Disclosure

Any interest or relationship, financial or otherwise that might be perceived as influencing an author's objectivity is considered a potential source of conflict of interest. These must be disclosed when directly relevant or directly related to the work that the authors describe in their manuscript. The existence of a conflict of interest does not preclude publication. If the authors have no conflict of interest to declare, they must also state this at submission. It is the responsibility of the corresponding author to review this policy with all authors and collectively to disclose all pertinent commercial and other relationships during submission.

3.7 References

References must be numbered in order of appearance in the text (including table captions and figure legends) and listed individually at the end of the manuscript. We recommend preparing the references with a bibliography software package, such as EndNote, Reference Manager or Zotero to avoid typing mistakes and duplicated references. We encourage citations to data, computer code and other citable research material.

In the text, reference numbers should be placed in square brackets [ ], and placed before the punctuation; for example [1], [1–3] or [1,3].

The reference list should include the full title, as recommended by the ACS style guide. Style files for Endnote and Zotero are available.
