How to Submit

Before preparing a paper, authors should consult the Instructions to Authors to ascertain the general format required, such as the permitted word count for different article types.

Prepare a covering letter to the Editor, Professor Hindrik Mulder

The covering letter is a key part of an Editor’s appraisal of a paper. It should say why the study was done, what it showed and why it might be interesting to the readers of Diabetologia. In their covering letter authors should notify the Editor of any potentially overlapping papers in preparation, submission or published. Failure to disclose such information is considered grounds for automatic rejection. Please also include details of any preprint posting, including DOI and licensing terms, if applicable. Authors must disclose, both in their manuscript and cover letter, any use of artificial intelligence (AI)-assisted technologies (such as Large Language Models [LLMs], chatbots or image creators).
