The European Journal of Endocrinology (EJE) acknowledges the unprecedented challenge posed by the global COVID-19 pandemic, demanding a global medical response we could never have anticipated facing in our lifetime. EJE is committed to support the global endocrine community in this time of crisis.
We ask our authors to continue submitting manuscripts and revising them in line with the reviewers’ comments. Likewise, we ask our reviewers to still commit to reviewing manuscripts submitted to EJE. However, we will be very accommodating to authors and reviewers with regards to the urgent time constraints placed upon them, and provide you with more time for your tasks if you need it. Simply contact the Editorial Office and we will grant extensions to deadlines as required.
In turn we would ask you to be lenient with us if the turnaround time of EJE papers becomes slightly longer than you are used to.

Uploading your submission
- Author list – All authors must be listed on the title page and entered on the ScholarOne Manuscripts submission in the correct order. Ensure all author email addresses provided are valid. Author information entered into ScholarOne Manuscripts will be used to generate PubMed listings for published papers.
- Cover letter – This letter should introduce your paper and outline why your work is important and suitable publication at this time.
- File formats – Ensure all files are in the correct format for revised submissions. See ‘Preparation of Manuscripts’ for further instructions.
- Figures and tables – Ensure all figures and table files are present and correct, and that they display clearly in the pdf proof.
User account details
All submitting authors are required to link their ScholarOne account with their ORCID iD. The system will prompt the author to do this when creating the submission.
The journal also requests that all authors identified as ‘corresponding authors’ create and link an ORCID iD with their account on ScholarOne prior to article acceptance. We also encourage contributing authors to associate an ORCID iD with their ScholarOne account. Author ORCID iDs will be displayed on the published article.
Author email addresses
The journal requires an institutional email address is associated with the account of both the submitting author and corresponding author; please edit the associated ScholarOne accounts to include this before pressing 'submit'. Alternatively please provide an explanation as to why this is not available to the Editorial Office by contacting email@example.com
This policy has been adopted in order to verify the authenticity of article submissions and protect the integrity of European Journal of Endocrinology.

Clinical Practice Guidelines
Letters to the Editor
Supplementary data files intended for online publication should be submitted online via ScholarOne Manuscripts as ‘Supplemental File for Review’, and referred to as supplementary data in the text:
(Supplementary Table 1)
(Supplementary Figures 1 and 2)
Human subjects research
- Images taken from pathology slides
- Laparoscopic images
- Images of internal organs
- Ultrasound images
- Give the full binomial Latin names for all experimental animals other than common laboratory animals
- State the breed or strain and source of animals, and give details of age, weight, sex and housing
- Detail the procedures and anaesthetics used, including doses given
Experiments with genetically engineered mice
Human genotype–phenotype association studies
- Statistical analyses demonstrating the level of statistical significance of a finding should be published or at least available so that others can attempt to reproduce the reported results
- Explicit information should be provided about the study’s power to detect a range of effects
- The study should be epidemiologically sound, with careful accounting for potential biases in selection of subjects, characterization of phenotypes, comparability of environmental exposures (when possible) and underlying population structure in cases and controls
- Phenotypes should be assessed according to standard definitions provided in the report
- Associations should be consistent (within the range of expected statistical fluctuation) and reported for the same phenotypes across study subgroups or across similar phenotypes in the entire study group
- Significance should not depend on altering the quality control methods beyond standard approaches that could change inclusion or exclusion of large numbers of samples or loci
- Measures to assess the quality of genotype data should include results of known study sample duplicates or publicly available samples
- The results for concordance between duplicate samples (if applicable) as well as completion and call rates per SNP and per subject should be disclosed, along with rates of missing data
- A subset of notable SNPs should be evaluated with a second technology that verifies the same result with excellent concordance, because no technology is error-free
- Associations with nearby SNPs in strong linkage disequilibrium with the putatively associated SNP should be reported (and should be similar)
- The results of replication studies of previous findings should be reported even if the results are not significant
- Testing for differences in underlying population structure in case and control groups should be performed and reported
- Appropriate correction for multiple comparisons across all statistical tests examined should be reported. Comparison to genome-wide thresholds should be described. Similarly, for bayesian approaches, the choice of prior probabilities should be described
- In gene and protein symbols, substitute Greek letters with the corresponding roman letter, eg TGFBR2 not TGFβR2
- Avoid hyphens unless they are part of the approved symbol, eg IGF1 not IGF-1
- Use arabic rather than roman numerals, eg BMPR2 not BMPRII
Humans, non-human primates and domestic species
- Gene symbols should be in italics with all letters capitalised, eg SOX2
- Protein designations should be the same as the gene symbols but not italicised, eg SOX2
- Please use symbols approved by the HUGO Gene Nomenclature Committee (HGNC)
Mice and rats
- Gene symbols should be in italics with only the first letter capitalised, eg Sox2
- Protein designations should be the same as the gene symbols except that all letters should be capitalised and in roman (ie not italicised), eg SOX2
- Please use symbols approved by the International Committee on Standardized Genetic Nomenclature for Mice and the Rat Genome and Nomenclature Committee, which can be queried at the MGI website
Digital image integrity
Digital image guidelines
- No specific feature within an image may be enhanced, obscured, moved, removed, or introduced
- Adjustments of brightness, contrast, or colour balance are acceptable if and as long as they do not obscure or eliminate any information present in the original. Any such adjustments should be applied to the entire image
- Threshold manipulation, expansion or contraction of signal ranges and the altering of high signals should be avoided
- The legend to a digital image should state if and what digital modifications were applied
- Band intensity should be quantified from several independent experiments. If only a "typical" experiment is shown in the figure, authors should be prepared to provide unprocessed images of gels or blots at the request of the Editor-in-Chief.
- Extensively cropped images are not acceptable. Images can be cropped to enhance clarity of presentation, but should always contain at least two markers (one with a smaller, one with a larger molecular size than the band of interest) with their molecular sizes indicated.
- Producing spliced images by combining lanes from gels or blots from different experimental runs should be avoided. A lane containing markers should be on the same gel for each run. If spliced images are presented, the vertical lanes obtained from gels or blots from different experimental runs should be clearly demarcated with lines.
- As the validity of immunoblots relies heavily on antibody specificity, an appropriate control (tissue from knockout mice or protein knockdown in cell lines) must be included, or alternatively a reference should be given in the methods section referring to such a control (Saper 2009; Burry 2011).
- The reuse of images of loading controls from other experiments or previous publications is unacceptable.
- Describe the numbers of experimental units used and the way in which they have been allocated to treatments
- Justify the omission of any observations from the analysis
- Describe methods of analysis precisely and state any necessary assumptions, as these may affect the conclusions that can be drawn from the experiment
