EDITORIAL
The choice of content is up to the Editor-in-Chief or someone he/she designates. Short essay containing information on important and topical issues related to articles or topics published in the scientific community, within the interest of the editorial policy.
ORIGINAL ARTICLES
They contain results of scientific research within the editorial line of the Journal. Authors may decide how to submit their research (original articles or short original articles); however, the journal may suggest format changes in the manuscript review process, taking into consideration the objectives, design and results of the research conducted.
They must comply with the following structure: abstract, key words, introduction, materials and methods, results, discussion and bibliographical references.
- Abstract. Written in Spanish and English. For Original Articles, it should be structured in: objectives, materials and methods, results and conclusions. Key words should be included at the end of each abstract. A minimum of three and a maximum of five should be proposed, in Spanish and English. The "descriptors in health sciences" - DeCS of BIREME (http://pesquisa.bvsalud.org/portal/decs-locator/?lang=es) and in English MeSH of the NLM (https://meshb.nlm.nih.gov/search) should be used.
- Introduction. It should be brief (less than 20% of the total length of the article) and include information on the current state of the health problem, background, justification and objectives of the study.
- Materials and methods. Describe the methodology used to allow the reproduction of the study and the evaluation of the quality of the information. It is recommended to review the international consensus for the presentation of articles according to study designs, for example, STROBE for observational studies, STARD for diagnostic tests, CONSORT for clinical trials, PRISMA for systematic reviews, SRQR for qualitative studies, CHEERS for economic evaluations, which can be found at equator-network.org
- The following subheadings may be used:
- Study design. Including the type of study, date and location of the study.
- Study population, includes its relevant characteristics, selection criteria, sample size or power calculation as appropriate, sample design and enrollment.
- Variables, describe the main study variables (dependent and independent) and specify their definition and form of measurement, indicating the validity of the method used with the corresponding citations.
- Procedures or interventions, describe the details of the interventions performed.
- Ethical aspects, describe the approval by ethics committees, permissions obtained, informed consent/assent, confidentiality of data, return of results if applicable.
- Data analysis, describes the treatment of the data, from the quality control of the database, statistical program, p value used as significant, the tests used for the crossing of which variables, information on the fulfillment of assumptions and how the models for multiple variables were developed if used.
- The following subheadings may be used:
- Results. Clearly presented, without including opinions or interpretations, except for those of a statistical nature. Tables and texts should have a call in the text, without repeating information. They may include subtitles to facilitate their presentation.
- Discusion. Interpretation and analysis of the main results, which respond to the objectives of the study, compare them with other studies, present differences or similarities, and explain the reason for them. It presents the limitations (biases) explaining why they do not invalidate the findings. It details the clinical implications of its findings, ending with conclusions (in response to the objectives) and recommendations.
- Referencesthat were cited in the article.
SHORT ORIGINALS
