Abstract: The abstract of original articles is a structured abstract, which includes the following four parts: objective, methods, results and conclusions. The total number words of abstract are no more than 400 words.
Key words: List 2-5 key words according to MeSH.
Methods: It should include and describe the following aspects:
Ethics: When reporting studies on human beings, indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional or regional) and with the Helsinki Declaration. For prospective studies involving human participants, authors are expected to mention about approval of regional/ national/ institutional or independent Ethics Committee or Review Board, obtaining informed consent from adult research participants and obtaining assent for children aged over 7 years participating in the trial. The age beyond which assent would be required could vary as per regional and/ or national guidelines. Ensure confidentiality of subjects by desisting from mentioning participants’ names, initials or hospital numbers, especially in illustrative material. When reporting experiments on animals, indicate whether the institution’s or a national research council’s guide for, or any national law on the care and use of laboratory animals was followed.
Evidence for approval by a local Ethics Committee (for both human as well as animal studies) must be supplied by the authors on demand. Animal experimental procedures should be as humane as possible and the details of anesthetics and analgesics used should be clearly stated. The ethical standards of experiments must be in accordance with the guidelines provided by the World Medical Association Declaration of Helsinki on Ethical Principles for Medical Research Involving Humans for studies involving experimental animals and human beings, respectively. The journal will not consider any paper which is ethically unacceptable. A statement on ethics committee permission and ethical practices must be included in all research articles under the ‘Methods’ section.
Study design: Describe your selection of the observational or experimental participants (patients or laboratory animals, including controls) clearly, including eligibility and exclusion criteria and a description of the source population.
Identify the methods, apparatus (give the manufacturer's name and address in parentheses), and procedures in sufficient detail to allow other workers to reproduce the results.
Give references to established methods, including statistical methods (see below); provide references and brief descriptions for methods that have been published but are not well known; describe new or substantially modified methods, give reasons for using them, and evaluate their limitations. Identify precisely all drugs and chemicals used, including generic name(s), dose(s), and route(s) of administration.
Reports of randomized clinical trials should present information on all major study elements, including the protocol, assignment of interventions (methods of randomization, concealment of allocation to treatment groups), and the method of masking (blinding), based on the CONSORT Statement.
Statistics: Quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals). Authors should report losses to observation (such as, dropouts from a clinical trial). When data are summarized in the Results section, specify the statistical methods used to analyze them. Specify the computer software used. P values are encouraged to be reported as the exact value or less than 0.05 or 0.01. Mean differences in continuous variables, proportions in categorical variables and relative risks including odds ratios and hazard ratios should be accompanied by their confidence intervals.
Results: Present your results in a logical sequence in the text, tables, and figures, giving the main or most important findings first. Do not repeat in the text all the data in the tables or figures; emphasize or summarize only important observations.
When data are summarized in the Results section, give numeric results not only as derivatives (for example, percentages) but also as the absolute numbers from which the derivatives were calculated, and specify the statistical methods used to analyze them. Restrict tables and figures to those needed to explain the argument of the paper and to assess its support. Use graphs as an alternative to tables with many entries; do not duplicate data in graphs and tables. Where scientifically appropriate, analyses of the data by variables such as age and sex should be included.
Discussion: Include summary of key findings (primary outcome measures, secondary outcome measures, results as they relate to a prior hypothesis); Strengths and limitations of the study (study question, study design, data collection, analysis and interpretation); Interpretation and implications in the context of the totality of evidence; Controversies raised by this study; and Future research directions (for this particular research collaboration, underlying mechanisms, clinical research).
Do not repeat in detail data or other material given in the Introduction or the Results section. In particular, contributors should avoid making statements on economic benefits and costs unless their manuscript includes economic data and analyses. Avoid claiming priority and alluding to work that has not been completed. New hypotheses may be stated if needed, however they should be clearly labeled as such. About 30 references can be included.
3.2.4. Reviews
It is expected that these articles would be written by individuals who have done substantial work on the subject or are considered experts in the field.
3.3. References
Authors are responsible for the accuracy and completeness of their references and for correct citation of the text. References should be numbered consecutively in the order in which they are first mentioned in the text (not in alphabetic order). Identify references in text, tables, and legends by Arabic numerals in superscript before the punctuation marks. References cited only in tables or figure legends should be numbered in accordance with the sequence established by the first identification in the text of the particular table or figure. The titles of journals should be abbreviated according to the style used in Index Medicus. Avoid using abstracts as references. Information from manuscripts submitted but not accepted should be cited in the text as “unpublished observations” with written permission from the source. Avoid citing a “personal communication” unless it provides essential information not available from a public source, in which case the name of the person and date of communication should be cited in parentheses in the text.
The commonly cited types of references are shown here. Number references in the order they appear in the text; do not alphabetize. In text, tables, and legends, identify references with superscript Arabic numerals. When listing references, abbreviate titles of journals according to Medline.
3.4. Tables
· Tables should be self-explanatory and should not duplicate textual material.
· Number tables, in Arabic numerals, consecutively in the order of their first citation in the text and supply a brief title for each.
· Place explanatory matter in footnotes, not in the heading.
· Explain in footnotes all non-standard abbreviations that are used in each table.
· Obtain permission for all fully borrowed, adapted, and modified tables and provide a credit line in the footnote.
· For footnotes use the following symbols, in this sequence: a, b, c, d, e, f , g, h, i.
3.5. Figures
Upload the images in JPG format. The file size should be within 1024 kb in size while uploading.
Figures should be numbered consecutively according to the order in which they have been first cited in the text.
Labels, numbers, and symbols should be clear and of uniform size. The lettering for figures should be large enough to be legible after reduction to fit the width of a printed column.
Symbols, arrows, or letters used in photomicrographs should contrast with the background and should be marked neatly with transfer type or by tissue overlay and not by pen.
Titles and detailed explanations belong in the legends for figures not on the figures themselves.
When graphs, scatter-grams or histograms are submitted the numerical data on which they are based should also be supplied.
The photographs and figures should be trimmed to remove all the unwanted areas.
If photographs of individuals are used, their pictures must be accompanied by written permission to use the photograph.
If a figure has been published elsewhere, acknowledge the original source and submit written permission from the copyright holder to reproduce the material. A credit line should appear in the legend for such figures.
The Journal reserves the right to crop, rotate, reduce, or enlarge the photographs to an acceptable size.
3.6. Protection of Patients' Rights to Privacy
Identifying information should not be published in written descriptions, photographs, sonograms, CT scans, etc., and pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian, wherever applicable) gives written informed consent for publication. Authors should remove patients’ names from figures unless they have obtained written informed consent from the patients.
