Only article types that appear in the drop-down menu during the submission process are available for submission to the selected section.

Please refer to your preferred journal and section to clarify which article types are available.

Ensure that any manuscript you submit conforms to the Committee on Publication Ethics (COPE) and the International Committee of Medical Journal Editors (ICMJE) recommendations for ethics, as well as to the general Frontiers article requirements.

Original Research articles are peer-reviewed, have a maximum word count of 12,000 and may contain no more than 15 Figures/Tables. Authors are required to pay a fee (A-type article) to publish an Original Research article. Original Research articles should have the following format: 1) Abstract, 2) Introduction, 3) Materials and Methods, 4) Results, 5) Discussion.

Systematic Review

Systematic Review articles present a synthesis of previous research, and use clearly defined methods to identify, categorize, analyze and report aggregated evidence on a specific topic. Included in this article type are meta-syntheses, meta-analyses, mapping reviews, scoping reviews, systematic reviews, and systematic reviews with a meta-analysis. Systematic Review articles are peer-reviewed, have a maximum word count of 12,000 and may contain no more than 15 Figures/Tables. Authors are required to pay a fee (A-type article) to publish a Systematic Review article. Systematic Reviews should: clearly define the research question in terms of population, interventions, comparators, outcomes and study designs (PICOS), and state which reporting guidelines were used in the study. For design and reporting, systematic reviews must conform to the reporting guidelines (e.g., PRISMA, Cochrane, Campbell), and include the PRISMA flow diagram http://prisma-statement.org/prismastatement/flowdiagram.aspx (if applicable), as well as funding information (if no specific funding to carry out the research, please state so). Systematic Reviews should have the following format: 1) Abstract, 2) Introduction, 3) Methods (including study design; participants; interventions; comparators; systematic review protocol; search strategy; data sources; study sections and data extraction; data analysis), 4) Results (including a flow diagram of the studies retrieved for the review; study selection and characteristics; synthesized findings; assessment of risk of bias), 5) Discussion (including summary of main findings; limitations; conclusions). Systematic Reviews must not include unpublished material (unpublished/original data, submitted manuscripts, or personal communications) and may be rejected in review or reclassified, at a significant delay, if found to include such content.

Correction

Corrigendum/Addendum: should authors notice errors that affect the scholarly record or the integrity of the paper, authors are encouraged to submit a correction online. The correction must detail the reason(s) for the error(s) and include only the elements (e.g. sections, sentence, figure) of the manuscript being revised or corrected. All authors of the original paper need to agree to the request for changes. The contribution to the field statement should be used to clearly state the reason for the Correction. Depending on the extent of the correction required, corrections may require peer review. Authors are informed that requests for changes beyond that described here may not be accepted for publication.

Erratum: should authors notice differences between their approved galley proofs and the final published article, thus leading to errors that affect the scholarly record or the integrity of the paper, authors are encouraged to submit a request for erratum to the Frontiers Production Office (production.office@frontiersin.org), clearly specifying the error and the correct information.

Editorial

Editorials are submitted exclusively by the host editor(s) of a Frontiers Research Topic, to convey to the reader the aims and objectives of the research that pertains to the topic, as well as placing it in a broader context. The Editorial should present the contributing articles of the Research Topic but should not be a mere table of contents. As the final contributing article to the Research Topic, Editorials should be submitted once all expected articles have been accepted and published. Editorials should not include unpublished or original data and the inclusion of references is strongly encouraged. Editorial articles may contain 1 Figure and have a word count of 1,000 for Topics with 5-10 articles. The word limit can be increased for each additional article in the Topic, up to a maximum of 5,000 words for 50 articles or more. Topic editors are not required to pay a fee to publish an Editorial article. Submissions are required to have the title Editorial: "Title of Research Topic".
