Manuscript Preparation Guideline


Authors may also refer to the International Committee of Medical Journal Editors (ICMJE)'s "Manuscript Preparation" guidelines for additional advice on appropriate manuscript preparation.


Structure and Presentation

The manuscript should be written as concisely as possible. Focus on the content rather than the look of the manuscript. Please refer to the prescribed word limit in the section “INSTRUCTION FOR SUBMISSION” for specific manuscript category.

Use at least single line spacing throughout, including in the references and figure legends. Use a common font such as Verdana, Arial, Helvetica, or Times in size 11 or 12 points. Avoid using manuscript formatting except for italic, superscript and subscript.

For section and subsection headings, please use the heading styles built into your word processing template to a maximum of three levels.

 All papers must contain the following items, when applicable: 


Title Page

The title page should include the following:

  1. The title of the article (150 characters maximum, using sentence case). It should reflect the content of the article.
  2. Full names of the authors (last, given, middle initial), with academic degree(s) attained or registration; avoid including affiliation title e.g. Member, Diplomate, Fellow etc. Correct: Zamora, Ma. Norma V. MD. Incorrect: J.A. Smith MD FRCP.
  3. The affiliation for each author. For each affiliation, include the name of the department (if any), the institution, the city, the province and country where the work was done. Link the authors to their designations using these characters in the order shown: * (asterisk, never superscripted) ** double asterisk and so on.
  4. At least three potential reviewers (name, affiliation and email address), who could, in the author’s opinion, expertly review the manuscript. The Editors, however, reserve the right to choose all reviewers. These reviewers should not have published with any of the co-authors during the past 2 years and should not currently work or collaborate with one of the institutes of the co-authors of the submitted manuscript.
  5. A shortened version of the title for use as a running header (no more than 60 characters, upper case).
  6. The full name of the corresponding author, with postal address, e-mail address, and fax and telephone numbers.
  7. Acknowledgments of grant support and of individuals who were of direct help in the preparation of the study or the manuscript. State also if there is none.
  8. A word count for the text only (excluding abstract, acknowledgments, figure legends, and references).
  9. The number of figures and tables.
  10. List of meeting/s or scientific forum where the materials have been previously presented or is under consideration for presentation. Indicate the name, place, date of meeting and any prize or awards

Use these subheadings:

  1. Background or Objective

      • - Study design
      • - Setting
      • - Subjects, participants, patients or population
  1. Results
  2. Conclusions (or Summary)

 After the abstract, list up to eight key words or phrases for journal (not library database) indexing. A list of key words is required for all submissions except editorials and commentaries. Present the key words in one paragraph, separated by commas, with no terminal punctuation.

Multi-word phrases used frequently (four times or more) in the text may be abbreviated if necessary. Introduce the abbreviation in parentheses after the first occurrence of the phrase, [for example, “chronic kidney disease (CKD)”. Note that sentences may never begin with an abbreviation.

Abbreviations for units of measurement and standard scientific symbols (for example, 3 mL, Na, BUN) may be used without explanation.


Units of Measurement

Use the SI system, and its standard symbols, throughout the manuscript. When units other than SI units are widely used, they can be indicated in parentheses after the SI unit.


Dates and Times

All dates are to be presented in the form Month dd yyy: for example, September 25, 2017. Times are to be presented using the 24-hour clock., using “h” as a separator between the hour and the minutes: for example, 8h30, 17h00.


Proprietary and Generic Names

Use generic names for all drugs.



Provide direct references to original research sources when possible and if available Digital Object Identifiers (DOIs) or URL. Avoid using abstract as references.

The manuscript’s reference list must be numbered (using Arabic numerals) consecutively in the order in which the references are first cited in the text. Citations appearing in tables and figures must fit into the numbering sequence from the point at which the table or figure is first mentioned in the text.


Reference style and format: please consult –



Figures for reproduction should approximately fit within the typeset area of the journal. The following resolutions are optimal:

  • Black-and-white line drawings, 600–1200 dpi
  • Line drawings with some grey or coloured lines, 600 dpi
  • Illustrations and photographs, 300 dpi

Authors should supply electronic versions of the figure content in EPS, GIF, TIFF, or JPEG format. Other formats, such PDFs, may be used, but are not preferred. Drawings in made in Microsoft Word and Powerpoint are discouraged, because the display of such drawings may not be reproduced as intended by the author.



Authors are asked to keep each table to a reasonable size; minimize the use of abbreviations, and if abbreviations must be used, use only well-known and accepted forms. The same data should not be presented in both a table and a figure.

 Tables are to be numbered using uppercase roman numerals (I, II, III, and so on) in the order in which they are cited in the article text. Tables should also have a title (above the table) that summarizes the whole table; it should be no longer than 15 words.
