Instructions for authors

To avoid delays during the revision process, read the instructions carefully and ensure that your manuscript length and format conform to ARP Rheumatology requirements before submitting.

The submission is divided into two main steps, described below.


First Step includes:

- Cover Letter to the Editor: This letter is mandatory.

- Corresponding author information: name; mailing address; phone number and email address.

- Manuscript identification: The title should briefly describe the paper's content. Avoid abbreviations in the title. A short running title should also be provided. Select the type of manuscript.

- Authors and affiliations: The author´s names and affiliations are mandatory. Up to three affiliations per author are possible.

- Suggested reviewers: you can provide up to three suggestions for reviewers, explaining why. The editor may or may not follow your suggestions.


Second Step includes:

- Abstract: A structured abstract with no more than 350 words summarizing the aims, methods, results and conclusions should be included. The word limit is 180 words for Case Reports.

- Keywords: A minimum of five keywords from the Journal’s list should be selected. These keywords are not the ones being published in the article (if accepted) but serve solely to support Editors to identify reviewers within the Journal’s database. 

- Title Page: As the Journal functions in a double-blind format, this file should include the title, the authors and their affiliations, ORCID, the information of the corresponding author, as well as the acknowledgements or other information suitable to identify the authors.

- File Manuscript: The manuscript should be uploaded (Word format: .doc or .docx), with the title, abstract and all sections of the manuscript. Please list the Tables and Figures at the end, after the references.

- Supplementary material: As a complement to the manuscript and in order to be available online, authors may submit supplementary material which should be essential to the integrity of the paper. The material is subject to the same editorial standards and peer-review procedures as the print publication and should be submitted in the Tables/Figures section as a .docx or PDF file. If the editorial board doesn’t consider it essential to the paper, publisher reserves the right to decline the publication of supplementary material. You can upload supplementary material for review only, i.e. not to be published (e.g. databases). These files will be collated in a single PDF.

- Informed Consent (for publication of identifiable material): please use this template (EN or PT) to collect the signatures, which should be uploaded when required.

- Figures/Captions: In addition to the inclusion of the figures in the main file of the manuscript, you should provide the original files of the pictures in order to allow the editorial team to publish them with the best resolution possible.
