Manuscript preparations

Font

The manuscript should be in Word document format (not as a PDF file). A manuscript including title page should be prepared with double-line spacing, wide margins 2.5 cm and the 12-fontTimes New Romans size. The abstract and text pages should have consecutive line numbers in the left margin beginning in the abstract and ending before the reference section. Number pages consecutively in the lower right-hand corner of each page, beginning with the title page. If your manuscript is or will be in .docx format and contains equations, you must follow the instructions below to make sure that your equations are editable when the file enters production.

If you have not yet composed your article, you can ensure that the equations in your .docx file remain editable in .doc by enabling "Compatibility Mode" before you begin. To do this, open a new document and save as Word 97-2003 (*.doc). Several features of Word 2007/10 will now be inactive, including the built-in equation editing tool.

The term diabetic should not be used as a noun. Do not use level when referring to a concentration. Use metric units of measure.

Title Page

Every manuscript, regardless of article type, must have an accompanying title page (authors and title). The full title must be 250 characters or fewer. Do not use abbreviations if possible. In the title only first letter of the first word should be capitalized.

Example:

- Shab-Bidar S, Neyestani TR, Djazayery A, Eshraghian MR, Houshiarrad A, Kalayi A, et al. Regular consumption of vitamin D-fortified yogurt drink (Doogh) improved endothelial biomarkers in subjects with type 2 diabetes: a randomized double-blind clinical trial

In addition to the title, the title page should include a short running title (less than 45 letters and spaces in length); the first name, middle initial, and last name of each author; affiliation of each author during the time the study was conducted; name, current address, telephone number, fax number, and e-mail address of the corresponding author; the word count, and number of tables and figures. The title page should also include a statement reporting any conflicts of interest, all sources of funding, the contribution of each author to the manuscript, a list of abbreviations and their definitions, registration number of clinical trials from clinical trials.gov and any ethical information as detailed above Table. The title page should be submitted as a separate page.

Abstract

Each original paper must have a structured and informative abstract not more than 250 words, with six paragraphs: Background, Objective, Methods, Results, and Conclusions. Abstracts should not include citations and abbreviations, if possible.

Trial registration

If your research article reports the results of a controlled clinical intervention, please list your trial registry, along with the unique identifying number (e.g. Trial registration: ClinicalTrials.gov: NCT01236846). Please note that there should be no space between the letters and numbers of your trial registration number. We recommend manuscripts that report randomized controlled trials following the CONSORT extension for abstracts. (http://www.consort-statement.org/index.aspx?o=1190)

Keywords

It is recommended to use up to six keywords; chosen from MEDLINE MeSH, for representing the main content of the article.

Introduction

A short introduction, not more than one page, is necessary. The Introduction should be concise and state the main research question and the purpose and importance of the study, with relevant references.

Materials/Subjects and Methods

Use materials for non-human and subjects for human studies (Materials/Methods or Subjects/Methods). This section should provide enough details to allow suitably skilled investigators to fully replicate your study. Specific information and/or protocols for new methods should be included in detail. If materials, methods (including statistical methods), and protocols are well established, authors may cite articles where those protocols are described in detail, but the submission should include sufficient information to be understood independent of these references. The methods section should include the design of the study, the setting, the type of participants or materials involved, a clear description of all interventions and comparisons, and the type of analysis used, including a power calculation if appropriate. Generic drug names should generally be used. When proprietary brands are used in research, include the brand names in parentheses.

For studies involving human participants a statement detailing ethical approval and consent should be included in the methods section. In papers reporting results of research using cell lines the origin of the cell lines should be mentioned.

Ethics

When reporting experiments on human subjects, indicate that the procedures followed were in accordance with the ethical standards of the responsible institutional or regional committee on human experimentation or in accordance with the Helsinki Declaration of 1975 as revised in 1983. Do not use patients’ names, initials, or hospital identification numbers. When reporting experiments on animals, indicate approval by the institution’s animal welfare committee and state whether the National Research Council’s guide for the care and use of laboratory animals was followed.

Statistics

Describe statistical methods with enough details. Use appropriate indicators (e.g., CIs, SDs, or SEs) to present your data even for differences that were not significant. Numbers of observations should be reported. Include general descriptions of statistical methods in the Subjects (or Materials) and Methods section and specific descriptions in each table and figure legend. Include testing for normality distribution and explain what you did for non-normally distributed data. Indicate the level of significance used in tests if different from the conventional 2-sided 5% alpha error and whether or what type of adjustment was made for multiple comparisons. Describe all computer software used for analyzing data including the version number and the manufacturer’s name and address.

Results

Results should be presented as concisely as possible, in a logical sequence with subheadings for subjects, measurements (for example, anthropometric measurements, laboratory investigations,..), text, figures or tables as appropriate. Avoid duplication of data from tables and figures in the text.

Discussion

Discussion should be started with the main findings of the study. The new and significant aspects of the study should be emphasized concisely and compared with previously published reports. There should be accordance between objectives and conclusions of your study. Please include strengths and limitations of the study. Make recommendations and potential future directions for research when warranted by the results. The Discussion should not exceed 4 typewritten pages. Do not repeat in detail data or other material given in the Introduction or Results. A clear conclusion should be drawn at the end of the discussion.

Acknowledgments

Acknowledgments should contain the author contributions paragraph??, brief statements of assistance, the guarantor's name (person[s] taking responsibility for the contents of the article), funding/financial support, and reference to prior publication of the study in abstract form, where applicable.

References

Details for statistics and non-standard abbreviations for study groups used in a figure should be defined in alphabetic order. Identify any symbols, numbers or letters used in the figures.

Tables

Each table should be inserted on a separate page at the end of the manuscript with the table number, title, and legend indicated. The title should clearly and concisely describe the treatments and experimental animals or human subjects (participants). Information regarding methods or explanatory material should be given as Table legend. Table legends should be inserted below the table and should not be included inside the table. Use "insert Table" in Word software for creating tables. Please use Times New Roman font, no smaller than 10-point.

Statistics of variability (e.g., SD, pooled SEM) and the significance of differences among the data should be shown. Apply the following sequence of symbols, from top to bottom, left to right: *, †, ‡, §, ||, ¶, #, **, ††, ‡‡ for more explanation of data of tables in Table legend.

Figures

Figures should be prepared in the following formats: PDF, TIFF, GIF, JPG, or BMP with a high resolution. Apply clearly labels and units of measure (where appropriate) for axes. Use letters and symbols to show significant differences. If figures have 2 or more panels, explain each panel in the legend, beginning with the panel letter. Panels should be the same height and/or width and so line up with one another vertically and/or horizontally, and should be submitted on a single page. Separate panels should be labeled A, B, C, D, etc. in the upper-left corner, near the graph. Text font size should be consistent both within each figure and among all figures in the document.
