RCBC uses double anonymous peer review, which means that authors' identities are hidden from reviewers and vice versa. Therefore, it is requested that the following documents be included separately:
Title page – must contain the study title and details about the authors. Thus, authors' names, affiliations, acknowledgments, and any disclaimer on conflicts of interest, in addition to the full address of the corresponding author, including the email address and ORCID of the first or last author must be included;
Main document containing the manuscript, without details of the authors or the institution where the study was carried out. This includes the main article body (including references, figures, tables, and any acknowledgments). No identifying information, such as authors' names or affiliations, should be included.
PREPARATION OF THE MANUSCRIPT:
1. The text must be in a single column format, keeping the formatting as simple as possible (preferably fonts Times New Roman or Arial, size 10 to 12, with double spacing between lines, and 2.5 cm top, bottom, and side margins). Bold, italic, subscript, superscript etc. can be used. When preparing tables, if using a table grid, apply only one grid for each individual table and not one grid for each row. If no grid is used, use tabs, without spaces, to align columns. To avoid unnecessary errors, it is recommended that the word processor's 'spell check' and 'grammar check' functions be used. Tables must be sent in a .doc or .docx file so they can be edited;
2. Title page: the study title should be concise and informative, avoiding abbreviations and formulas whenever possible. Clearly indicate the name(s) and surname(s) of each author and verify that all names are spelled correctly. Provide the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lowercase superscript immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the name of the country if the author is from outside Brazil. Clearly indicate who the corresponding author is at all stages of evaluation and publication, which implies the responsibility for answering any future questions about the study. Please ensure that an email address is provided and that the contact details are kept up to date by the corresponding author. Authors are those individuals who actually participated in its elaboration (http://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html);
3. Keywords: use three to 10 keywords, previously verified in the MeSH (Medical Subject Headings) terms. Remember that the greater the keywords scope, the greater the possibility that the article, if accepted, can be found on scientific search platforms;
4. Abstract: must start on the second page of the manuscript and comply with the maximum number of words for the type of article being submitted (See section Types of manuscript). It must be structured (following the same format as the article structure), direct and easy to read;
5. Text: Manuscripts must be previously unpublished (see preprints section) and sent in digital form, as described in editable formats (.doc, .docx) above. The same applies to tables and figures. Images must be sent in separate files, in .jpg, .gif, or .tif formats, in at least 300 dpi resolution, and with reference in the text about the place of insertion. Abbreviations should be as few as possible and limited to the terms mentioned repeatedly, as long as they do not alter the text understanding and should be defined at first use. Furthermore, the text should be divided into the following sections: Introduction, Methods (or Patients), Results, Discussion, and Conclusion(s). Other descriptive titles and subtitles may be used if deemed more appropriate, depending on the type of manuscript being submitted.
(i) Introduction: must be written based on the study question, explaining the problem that motivated it, according to the most recent literature, and end with the objective of the investigation. The formulation of a hypothesis is widely encouraged, which shows the authors' knowledge and involvement with the subject addressed in the study;
(ii) Methods (or Patients): In this section, the authors should provide details on patients’ inclusion and exclusion criteria, research method, evaluation or measurement systems, with appropriate references, and statistical analyzes used. Any equipment or apparatus used must be named, along with the model and manufacturer's address. Appropriate statistical analysis of all studies is encouraged, which increases the merit of observations, especially when a significant difference is observed. Approval by the Ethics Committee must be mentioned (except for those works that do not require it). The more details provided, the greater the transparency and the easier the reproducibility for other researchers who want to repeat/validate the study. Where relevant, tables or figures can be included to provide clearer information. No results should be presented in this section;
(iii) Results: must present the study’s relevant findings in a concise way and preferably with statistical analysis. The use of tables and figures is encouraged (maximum of six), in order to present the findings in a clearer and more noticeable way;
(iv) Discussion: should focus on comparing the study findings with the most relevant, preferably most current, literature, reviewing the results and possible confounding factors, sources of bias, study weaknesses, and pertinent literature review, and placing the study results in the context of previous work in the same area;
(v) Conclusion(s): must be based on the findings presented, answering the study question (study objective);
(vi) References: Must be predominantly from works published in the last five years, easily accessible to the reader (preferably electronic, with identification numbers such as DOI or PMID), and formatted in accordance with the Vancouver standards (Standards for Manuscripts Submitted to Biomedical Journals - ICMJE www.icmje.org – CIERM; example: Rev Col Bras Cir. 2008;35(6):425-41 - www.revistadocbc.org.br). If there are works with similar content, previously published in RCBC, we suggest evaluating such citations. Personal communications and annals of congresses will not be accepted as references. Book citations and book chapters are discouraged. The authors of the article are responsible for the references’ veracity. References must be listed in numerical sequence as they are cited in the text. Personal communications and unpublished data must be cited in parentheses in the text, and not included in the numbered reference listed at the end of the article. Quotes from someone other than the author (eg. personal communication) may only be published if there is a signed permission letter. Authors are strongly encouraged to verify the accuracy of each reference against the original source. Examples of references:
(a) Articles published in scientific journals: list all authors when there are six or less; in case of seven or more, list the first six and add “et al”. Do not repeat page numbers:
