REDUNDANT (DUPLICATE) SUBMISSION

It is recommended that Authors read the updated version of the statement on redundant submission, jointly published with other journals in 2015.

STATISTICAL AND DATA REPORTING GUIDELINES

It is highly recommended that Authors consult the guidelines on Statistical and data reporting; see also the corrigendum.

CLINICAL TRIALS

Registering clinical trials

In accordance with the Clinical Trial Registration Statement from the International Committee of Medical Journal Editors (ICMJE) all clinical trials published in the journal must be registered in a public trials registry at or before the onset of participant enrolment. For any clinical trials commencing prior to 1st July 2005, retrospective registration will be accepted.

The registry must be accessible to the public at no charge, searchable, open to all prospective registrants, managed by a not-for-profit organization, and include all the necessary information as specified by the ICMJE. A list of recommended registries can be found on the ICMJE website. Results posted in the same clinical trials registry in which the primary registration resides will not be considered as prior publication if they are presented in the form of a brief abstract (<500 words) or a table.

Authors are requested to provide the exact URL and unique identification number for the trial registration at the time of submission on the manuscript’s title page. This information will appear later in the published article.

Reporting clinical trials

Clinical trials should comply with the Consolidated Standards of Reporting Trials Statement (CONSORT), which is available here. Authors reporting on randomized clinical trials (RCT) should consult the CONSORT checklist when preparing their manuscripts. All RCT data will be evaluated in accordance with the rules and checklist of the CONSORT statement.

Other types of studies should follow guidelines where available. These include STARD (Standards for the Reporting of Diagnostic accuracy studies), STROBE (Strengthening the reporting of observational studies in epidemiology), PRISMA (Transparent Reporting of Systematic Reviews and Meta-Analyses) and MOOSE (Meta-analyses of observational studies). For further information on good reporting of health research studies please go to the EQUATOR network.

The relevant checklist should be duly filled in and uploaded as "Supplemental files".

Data sharing statements for clinical trials

This journal will require the following as conditions of consideration for publication of a clinical trial report:

As of 1 July 2018 manuscripts submitted to ICMJE journals that report the results of clinical trials must contain a data sharing statement. Full details can be found in Taichman et al Ann Intern Med. 2017;167:63–65. The data sharing statement should be mentioned in the text and uploaded as a Supplemental file.

Clinical trials that begin enrolling participants on or after 1 January 2019 must include a data sharing plan in the trial's registration. The ICMJE's policy regarding trial registration is explained here. If the data sharing plan changes after registration this should be reflected in the statement submitted and published with the manuscript, and updated in the registry record.

Abstract

An abstract should be a concise summary of the manuscript. Reference citations are not allowed. The abstract should be factual and free of abbreviations, except for SI units of measurement. A structured abstract must have four sections:

Objectives: should describe the problem addressed in the study and its purpose.

Methods: should explain how the study was performed (basic procedures with study materials and observational and analytical methods).

Results: should describe the main findings with specific data and their statistical significance, if possible.

Conclusions: should contain the main conclusion of the study.

Keywords

Following the abstract, 3-6 keywords should be given for subject indexing.

Main text

 Introduction

Should state the purpose of the investigation and give a short review of pertinent literature.

Materials and methods

Should be described in detail with appropriate information about patients or experimental animals. Use of abbreviations is forbidden. Generic names of drugs and equipment may be used in the manuscript, with brand names (proprietary name) and the name and location (city, state, country) of the manufacturer in brackets when first mentioned in the text.

Results

Results should be reported concisely and regarded as an important part of the article. They should be presented either in tables and figures, and briefly commented on in the text, or in the text alone.

Discussion

The discussion is an interpretation of the results and their significance with reference to pertinent work published by other authors. It should be clear and concise. The importance of the study and its limitations should be discussed.

Acknowledgement

Acknowledgements and details of non-financial support must be included at the end of the text before the references.

Funding statement

See Funding and conflict of interest section below.

Conflict of interest statement

See Funding and conflict of interest section below.

Figure (and video) legends

A list with legends for each figure (and each video) must be included.

Tables

All tables must be included in the manuscript file, as part of the text, not as images. All tables should start on separate pages and be accompanied by a title, and footnotes (use superscript a,b,c….) where necessary. The tables should be numbered consecutively using Arabic numerals. Abbreviations and their full definitions should be listed in alphabetical order at the bottom of the table. Avoid overcrowding the tables and the excessive use of words. The format of tables should be in keeping with that normally used by the journal; in particular, vertical lines, coloured text and shading should not be used. Please be certain that the data given in tables are correct. All tables must be cited in the text.

References

References should be numbered in order of appearance in the text (in Arabic numerals in parentheses (in superscript)) and must be listed numerically in the reference list. Journal titles and author initials should be abbreviated and punctuated according to PubMed. If an automatic referencing system has been used in the preparation of the paper, the references must not be left embedded in the final text file submitted. The citation of journals, books and articles published online should conform to the following examples:

All authors and co-authors should be mentioned. Personal communications (author, personal communication) must be authorized in writing by those involved, and unpublished data should be cited in the text as (unpublished data). References to manuscripts submitted, but not yet accepted, should be cited in the text as (authors, manuscript in preparation) and should not be included in the list of references. Authors are encouraged to cite web URLs in parentheses at the appropriate mention in the text.

FIGURES AND VIDEOS

All figures and videos require a legend and must be cited in the text.

Figures

Note: The requirements for online submission and for reproduction in the journal are the same.

Minimum resolutions are 300 dots per inch (dpi) for colour or tone images, and 1000 dpi for line drawings, supplied at a minimum width of 16.8 cm.

JHCVM does not redraw figures of accepted manuscripts. Figure preparation is the author's responsibility. See guidelines or go to http://cpc.cadmus.com/da.

The journal reserves the right to reduce the size of illustrative material. Any photomicrographs, electron micrographs or radiographs must be of high quality. Photomicrographs should provide details of staining technique and a scale bar, and must be in colour. Patients shown in photographs should have their identity concealed or should have given their written consent to publication. When creating figures, make sure any embedded text is large enough to read. Many figures contain miniscule characters such as numbers on a chart or graph. If these characters are not easily readable, they will most likely be illegible in the final version.

Colour illustrations

JHCVM encourages the use of colour figures when colour helps with the understanding of the figures. JHCVM does not charge for the publication of colour figures but the Editor may use his discretion when deciding which figures to publish in colour.

Videos

Where appropriate, video sequences may be submitted using standard digital video formats. Videos must be relevant and contain only vital/novel information. The total playback time for the videos should not exceed 5 minutes. Videos should be numbered in the order they appear in the text.

Format

Videos can be submitted in any standard format : wmv, avi, mpeg, mov, etc. Videos must be of high quality and must have a minimum size of 640x480 pixels (preferably higher as all videos will be converted to MP4 to JHCVM specifications). The aspect ratio can be: 4:3 or 16:9.

PERMISSION TO REPRODUCE FIGURES AND EXTRACTS

Permission to reproduce copyright material, for print and online publication in perpetuity, must be cleared and if necessary paid for by the author; this includes applications and payments to DACS, ARS and similar licensing agencies where appropriate. Evidence in writing that such permissions have been secured from the rights-holder must be made available to the editors. It is also the author's responsibility to include acknowledgements as stipulated by the particular institutions. Please note that obtaining copyright permission could take some time. Should you require copies of this then please contact the editorial office of the journal in question.

For a copyright prose work, it is recommended that permission is obtained for the use of extracts longer than 400 words; a series of extracts totalling more than 800 words, of which any one extract is more than 300 words; or an extract or series of extracts comprising one-quarter of the work or more.

FUNDING AND CONFLICT OF INTEREST STATEMENTS

Funding statement

Details of all funding sources for the work in question should be given in a separate section entitled 'Funding'. This should appear before the 'Acknowledgements' section.

The following rules should be followed:

• The sentence should begin: ‘This work was supported by …’
• The full official funding agency name should be given, i.e. ‘the National Cancer Institute at the National Institutes of Health’ or simply 'National Institutes of Health' not ‘NCI' (one of the 27 subinstitutions) or 'NCI at NIH’
• Grant numbers should be complete and accurate and provided in brackets as follows: ‘[grant number ABX CDXXXXXX]’
• Multiple grant numbers should be separated by a comma as follows: ‘[grant numbers ABX CDXXXXXX, EFX GHXXXXXX]’
