Below the abstract should provide 3 to 10 key word. Introduction State the purpose of the article and summarize the rationale for the study or observation. Methods Describe the selection of the observational or experimental subjects (patients or laboratory animals, including controls) clearly. Identify the age, sex, and other important characteristics of the subjects. Identify the methods, apparatus (give the manufacturer’s name and address in parentheses), and procedures in sufficient detail. Give references to established methods, including statistical methods; 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 randomised clinical trials should present information on all major study elements, including the protocol, assignment of interventions (methods of randomisation, concealment of allocation to treatment groups), and the method of masking (blinding), based on the CONSORT statement (Moher D, Schulz KF, Altman DG: The CONSORT Statement: Revised Recommendations for Improving the Quality of Reports of Parallel-Group Randomized Trials. Ann Intern Med. 2001;134:657-662, also available at http://www.consort-statement.org). Ethics When reporting studies on human, 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 of 1975, as revised in 2000 (available at http://www.wma.net/e/policy/17-c_e.html). Do not use patients’ 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 anaesthetics and analgesics used should be clearly stated. The ethical standards of experiments must be in accordance with the guidelines provided by the CPCSEA (animal) and ICMR (human). 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 ‘Materials and Methods’ section. Statistics Whenever possible, quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals). Report losses to observation (such as dropouts from a clinical trial). Put a general description of methods in the Methods section. When data are summarized in the Results section, specify the statistical methods used to analyse them. Avoid non-technical uses of technical terms in statistics, such as ‘random’ (which implies a randomising device), ‘normal’, ‘significant’, ‘correlations’, and ‘sample’. Define statistical terms, abbreviations, and most symbols. Use upper italics (P = 0.046). Results Present the results in logical sequence in the text, tables, and illustrations. Do not repeat in the text all the data in the tables or illustrations; emphasise or summarise only important observations. Discussion Emphasize the new and important aspects of the study and the conclusions that follow from them. Do not repeat in detail data or other material given in the Introduction or the Results section. Include in the Discussion section the implications of the findings and their limitations, including implications for future research. Relate the observations to other relevant studies. 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. State new hypotheses when warranted, but clearly label them as such. Acknowledgements As an appendix to the text, one or more statements should specify contributions that need acknowledging but do not justify authorship, such as general support by a departmental chair; acknowledgments of technical help; and acknowledgments of financial and material support, which should specify the nature of the support. This should be the last page of the manuscript. References 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. 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. Use the style of the examples below, which are based on the formats used by the NLM in Index Medicus. The titles of journals should be abbreviated according to the style used in Index Medicus. Use complete name of the journal for non-indexed journals. 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. Contributors should obtain written permission and confirmation of accuracy from the source of a personal communication.

Galley Proofs & Reprints: The research team of any study should assign one of the authors as a corresponding author. The editorial office will send him proofs of the manuscript for final proof reading and it will be his/her responsibility to return the galley proof materials appropriately corrected within the stipulated time. Proofs will not be accepted from any of the other authors without an accompanying authorization letter from the corresponding author. After the corresponding author has approved the galley proof, he/she will be responsible for any publication errors missed on the galley proof found after publication. No major change such as deletion, shortening, or expansion of sentences in the text will be accepted at this time. During the proofing process, no addition of information is allowed, however, if there is new relevant information to be added to the manuscript, this can be included as an addendum to the article. The corresponding author is required to sign on each page of the galley proof indicating his approval of any editorial amendments and agree that the meaning of his article has not been altered. It is the duty of the corresponding author to respond promptly to any query from the editors as failure to do so may result in delay of publication or simply rejection of the article. Papers will be published only when the finally accepted manuscript approved by the corresponding author or designated corresponding author is received in the editorial office. If a manuscript is sent out for proofing and no response is received from the corresponding author, this manuscript will be deferred for one issue only. The proof will be then be resent after one month and if there is still no response, the paper may be withdrawn from the journal. If the editorial office is able to proofread the article and answer any outstanding queries, it will be at the Editorial Board’s discretion to proceed with the publishing of the paper including a statement that this has not been proofread by the corresponding author. If there is substantial number of unresolved queries, then the paper may be withdrawn from the journal. Information for ordering reprints will be included when sending the galley proof and these must be ordered at this time, as they cannot be obtained after the journal is in-press.      Contributors' Form / Copyright form   Manuscript Title _______________________________________________________ Manuscript Number (for articles submitted online) _____________________________ I / We certify that I/we have participated sufficiently in the intellectual content, conception and design of this work or the analysis and interpretation of the data (when applicable), as well as the writing of the manuscript, to take public responsibility for it and have agreed to have my/our name listed as a contributor.
