j.  Additional considerations: tables, figures and other stylistic aspects

Place the tables and figures in the space you consider appropriate, and make the calls in correlative form according to the order in which they appear.

-     Tables

Tables should complement the information contained in the text, not duplicate it. Construct the tables with horizontal lines only and within the Word document (do not paste images), number them with Arabic numerals consecutively in the order of the first callout in the text, name each table with a concise and self-explanatory title, and employ table footnotes to explain the callouts within the table and all non-standard abbreviations.

If using data from another published or unpublished source, cite and reference the source. If necessary, obtain the corresponding permit.

-     Figures

Figures (photographs, images and graphics) shall be placed inside the Word file, being announced in the text only as «Figure» and numbered with Arabic numerals in correlative order. The figures shall not have titles, but you shall add captions, in which you can add information about the source, in case the figures are not of your authorship. It is the authors' responsibility to obtain permission for reproduction from the copyright holder.

Also note that all figures should be uploaded to the journal's manuscript submission system as separate, high-resolution files.

7. Other stylistic aspects

• Acronyms and abbreviations: should be used sparingly and only when it facilitates reading. The first time, use the full word followed by the abbreviation in parentheses (unless the abbreviation is standard usage), thereafter use only the abbreviation.
• Medications: should be referred to by their generic names.
• Measurement units: measurements of length, height, weight and volume in metric units (meter, kilogram or liter) or their decimal multiples shall be used. Temperatures should be in degrees Celsius. Arterial pressures should be expressed in millimeters of mercury.
• Numbers: for the Spanish wording, decimal fractions shall be separated from whole numbers by a comma; thousands and millions by a single space. For writing in English, decimal fractions shall be separated from whole numbers with a period.
• Statistics:   specify the statistical methods used.
