Original and review papers are prioritized over other types of materials. These
should be structured in the following manner: Introduction, Methods, Results and
Discussion. Each of these headings will be highlighted in the body of the paper.
In general, papers should not exceed 30 pages.
These papers should be accompanied
by an abstract written in an impersonal style, containing the objectives of the
research, the materials and methods used, and a brief description of the main
results and conclusions. Abstracts may be either unstructured or structured. Unstructured
abstracts should not exceed 150 words, whereas structured abstracts may contain
up to 250 words. Three to ten key words or phrases will be added to facilitate
indexing of the paper.
The introduction will define both the topic dealt with
in the paper and its background. The objectives of the study will also be stated,
as well as the justification of the research. Data and conclusions from the paper
will not be included.
The section devoted to methods will describe the materials
used, inclusion and exclusion criteria for the entities studied, the composition
and essential characteristics of the samples analyzed, as well as the procedures
and statistical techniques (sampling type, tests, etc.) used for quality control,
always under the basic principle that a specialist with a background similar to
that of the author should be able to reproduce the study without using any information
apart from that provided by the author about how the study was conducted and the
original data used. In the case of well known methods, reference will be provided
to papers where they are thoroughly described. If they are less well known, a
brief description should be included. When unknown methods are used, besides providing
thorough information about them, the reasons, advantages and disadvantages of
their use will be expounded. The software used for data processing should be specified.
results will be presented in a logical sequence, and will include only the relevant
statistics and graphs necessary to present the most important information in accordance
with the objectives of the paper. The information contained in tables and figures
will not be repeated in the text. Figures will be an alternative to tables; data
should not be duplicated in tables and figures. The use of either should reflect
their capacity to facilitate understanding of the information and the economy
of the journal. Claiming of intellectual priority of the contents presented should
be avoided, as well as any reference to incomplete research.
The section devoted
to discussion will deal with findings obtained by the study. Conclusions will
be expounded in accordance with the objectives of the research. Reference will
be made to the significance of the results, as well as their limitations in relation
to similar research. The contents described in the introduction and the results
will not be repeated. Unjustifiable conclusions or extrapolations of the data
used will be avoided.
Bibliographic references will follow the recommendations
of the Vancouver style, and will be listed at the end in the same order as they
appear in the text.
