Scope and Article Types

JEH publishes original research, clinical studies, systematic reviews, meta analyses, and translational investigations across endocrine and metabolic medicine.

Submissions should focus on hormone regulation, endocrine disorders, metabolic pathways, diagnostics, therapies, or clinical outcomes relevant to endocrine care.

• Original research and clinical trials
• Observational studies and cohort analyses
• Systematic reviews and meta analyses
• Case series with actionable clinical insight
• Methods papers and technical innovations
• Guidelines and consensus statements

Manuscript Structure

A typical manuscript should include a title page, abstract, keywords, main text, references, tables, and figures. Use headings to separate Introduction, Methods, Results, and Discussion.

Provide a concise abstract that summarizes the objective, design, key findings, and clinical relevance. Include 4 to 7 keywords aligned with endocrine terminology.

Reporting Standards

JEH encourages authors to follow established reporting guidelines to improve clarity and reproducibility. Include checklist references where relevant.

• CONSORT for randomized trials
• STROBE for observational studies
• PRISMA for systematic reviews
• CARE for case reports
• ARRIVE for animal research

Ethics and Consent

Human studies require ethics committee approval and documented informed consent. Animal studies should comply with institutional animal care requirements.

Include approval identifiers and consent statements in the Methods section. Studies lacking clear ethical documentation may be returned without review.

Clinical Trial Registration

Prospective clinical trials should be registered in a recognized registry. Provide the registration number and registry name in the manuscript.

Data and Code Availability

Provide a data availability statement that explains where supporting datasets can be accessed or why access is restricted. If code or scripts are essential to the analysis, describe how they can be accessed.

• Use trusted repositories such as Dryad, Zenodo, OSF, or institutional platforms
• Ensure patient privacy and comply with data protection laws
• Explain embargoes or controlled access where needed

Figures, Tables, and Supplementary Material

Figures and tables should be clear, labeled, and referenced in the text. Provide high resolution images and ensure legends describe methods and outcomes.

Supplementary materials should include essential methods, extended data, or additional analyses that support the main conclusions.

Authorship and Contributions

List all authors who meet accepted authorship criteria and describe individual contributions. Ensure the corresponding author has authority to speak for all coauthors.

Include ORCID identifiers when available to support accurate attribution.

Conflicts of Interest and Funding

Disclose financial, institutional, or personal relationships that could influence interpretation of results. Include all funding sources and grant numbers in a dedicated statement.

References and Citations

Use a consistent citation style and ensure references are complete. Verify DOI links and cite primary sources for key findings. Excessive self citation should be avoided.

Revision and Proofing

Respond to reviewer comments with a point by point response. Highlight changes in the revised manuscript to assist evaluation.

After acceptance, authors review proofs for accuracy of data, figures, and author details.

Language and Style

Write in clear scientific English and define specialized endocrine terms on first use. Avoid unexplained abbreviations and ensure consistency in units and nomenclature.

If English is not your first language, consider language editing prior to submission.

Statistical Reporting

Describe statistical methods in sufficient detail to allow replication. Report effect sizes, confidence intervals, and p values as appropriate.

Clinical Relevance

Clarify how results apply to patient care, diagnosis, or therapy. Discussion sections should address limitations and real world applicability.

Supplementary Data

Large datasets, protocols, or extended tables can be included as supplementary files. Ensure supplementary materials are referenced in the main text.

Cover Letter

Provide a concise cover letter that explains the novelty, clinical relevance, and fit to JEH. Mention any prior presentations, preprints, or related submissions to support transparency.

Title Page Details

Include full author names, affiliations, corresponding author contact, and ORCID identifiers. Note author contributions and confirm that all authors approve the submission.

Abstract Format

Use a structured abstract when possible, with objective, methods, results, and conclusions. Highlight primary outcomes and endocrine relevance for discoverability.

Units and Nomenclature

Report measurements using SI units and standard endocrine terminology. Use consistent naming for hormones, receptors, and biomarkers across text, tables, and figures.

Abbreviations

Define abbreviations at first use and avoid excessive acronym use. Abbreviations should improve clarity rather than reduce readability.

Figures and Image Integrity

Ensure figures are unaltered except for uniform adjustments and include scale bars when needed. Provide source data for key image based results when possible.

Clinical Trial Details

For trials, include registration numbers, primary outcomes, and protocol deviations. Describe randomization, blinding, and allocation methods when applicable.

Animal Studies

Describe animal model selection, housing conditions, and humane endpoints. Report sex, age, and number of animals used with justification.

Patient Privacy

Remove identifying information from images or case descriptions unless explicit consent is provided. Note consent procedures for case reports and clinical images.

Preprints and Prior Posting

JEH allows prior posting on non peer reviewed preprint servers. Disclose the preprint DOI and ensure the submitted manuscript reflects any subsequent updates.

Plagiarism and Originality

All submissions are screened for originality. Reuse of text or figures must be properly cited, and redundant publication is not permitted.

Data Sharing Compliance

Include accession numbers for public datasets and explain restrictions for controlled access data. Ensure repository links are active at submission or by acceptance.

Author Order and Changes

Confirm author order before submission. Any changes after submission require written approval from all authors and a clear rationale.

Open Researcher Identifiers

Provide ORCID identifiers to improve author attribution and metadata accuracy. ORCID is recommended for corresponding authors.

Tables and Data Presentation

Tables should be editable and not embedded as images. Use clear headings and define all abbreviations in table notes. Report units and reference ranges for endocrine biomarkers.

Graphical Abstracts

If provided, graphical abstracts should summarize the key finding visually and align with the manuscript conclusions. Keep text minimal and ensure legibility at small sizes.

Statistical Power

Explain sample size calculations or justify cohort sizes when power calculations are not feasible. Include rationale for subgroup analyses to avoid over interpretation.

Biospecimens and Tissue Studies

For studies using human tissue or biospecimens, describe collection protocols, consent procedures, and storage conditions. Confirm institutional approvals for biobanks or repositories.

Video and Multimedia

If multimedia files are used to demonstrate procedures or imaging, provide captions and context. Ensure files are anonymized and referenced in the main text.

Reference Management

Use a consistent reference format and verify all citations. Include DOIs when available and cite primary sources for key endocrine findings. Avoid excessive self citation.

Clinical Endpoints

Clearly define primary and secondary endpoints, including laboratory and clinical outcomes. Provide rationale for endpoint selection to support reviewer evaluation.

Supplementary Protocols

When protocols are complex, include full methods in supplementary files or a protocol repository. This helps readers replicate studies and apply techniques in future research.

Clinical Data Transparency

Describe data cleaning, missing data handling, and sensitivity analyses. Transparent reporting strengthens confidence in endocrine outcomes and supports evidence synthesis. Provide clear cohort flow diagrams when applicable. State any protocol deviations and their impact on results. Include confidence intervals where relevant. Report sensitivity analyses clearly for transparency and data interpretation and reproducibility overall.
