Tables and Figures: No more than 6 tables and/or figures will be regularly accepted (exceptions may be discussed). Tables or Figures used from another published source (either exactly or closely adapted) require written permission from the publisher. It is the author's responsibility to obtain this permission upon acceptance of the manuscript by Archives of Medical Research. Elsevier will not publish any material that has been previously published without this permission. Manipulation of images for the purposes of deception or fraud is considered an ethical abuse and precludes the suspension of authors to publish again in this journal.

Take into account the following recommendations: Tables and figures must include their legends

  • Tables and figures must be sent separately.

  • Tables should be formatted in a word processing package and must be double spaced. Each table should be included on a separate page.
  • Tables should be self-contained and self-explanatory.
  • Provide a title for each table and use Arabic numerals.
  • Do not use vertical lines to separate information within the table.
  • Avoid the use of both tables and graphs to illustrate the same results and similarly, avoid detailed description of information in either within the text if that information can be easily observed in the tables and figures.
  • Use superscript letters for table legends.

Illustrations. Original illustrations should be professionally designed, in two dimensions, separately from the text (tables are included with the text), and submitted with the manuscript in recent versions of software programs. (Elsevier recommends that only JPEG, EPS, or PDF formats be used for electronic artwork.) Figure size must be at least 8.5 cm (maximum 17.6 cm) in width. Resolution of the jpg images must be at least 300 dpi. Color illustrations are encouraged; however, the cost of color printing is at the author's expense and arranged directly with the publisher ( The electronic version will contain color illustrations.

References: Accuracy of references is the responsibility of the authors. Copy authors' names, article titles and other publisher information. Take into account the following instructions:

  • Confirm that all references mentioned in the text are presented in the Reference section at the end of the paper (and vice versa).
  • References mentioned within text should be presented in Arabic numbers in parentheses and appear before the ending punctuation if at the end of the sentence.
  • Do not superscript reference numbers.
  • References are numbered sequentially in the text.
  • The Reference list at the end of the paper should be numbered in the order as mentioned in the text and must match the in-text citation.
  • Limit the number of authors listed to three, after that, use et al.
  • References may contain only published works and papers in press.
  • Works in progress, manuscripts submitted but not yet accepted, unpublished data, and personal communications may only be acknowledged (in parentheses) within the text (including year).

All the references should be listed numerically in Vancouver format, according to the order of appearance in the text. Identifying references in the text using parenthesis in superscripts.
