Authorship recognition can only be dependent on valuable contributions each of the following three components:

  1. Concept and design of study or acquisition of data or analysis and interpretation of data;
  2. Drafting the article or revising it critically for important intellectual content; and
  3. Final approval of the version to be published.

Participation exclusively in fundraising or data collection does not validate authorship. Research community generalized supervision is not necessary for authorship. Every author would have been adequately active in the work that takes legal responsibility for relevant portions of manuscript material. The order in which authors are named will be based on the participant's potential influence to the analysis and writing the paper. After the order has been issued, it cannot be amended without any of the written permission of all stakeholders. The journal recommends as many writers as possible for manuscripts based on the type of manuscript, its nature and numbers of organizations involved.

Contribution details

Authors should identify the benefits offered towards the manuscript by each of them. Description should be divided into the following categories as applicable: concept, architecture, interpretation of intellectual material, literature review, clinical trials, research designs, data collection, statistical analysis, preparation of manuscripts, editing of manuscripts and manuscripts.


All authors of must report any and all potential conflict of interest they may have about the publication of the manuscript or of an entity or product specified in the manuscript and/or relevant to the results of the work presented. Authors also should report potential conflicts with items in the manuscript which interact with all those listed.


All manuscripts must be submitted on-line through the website OUR LINK Users will have to register at this platform for the first time. Registration is free and secure, but is mandatory. Registered authors are able to keep track of their posts utilizing their login details after signing into website.

Manuscripts must be prepared in accordance with the "Uniform Manuscript Criteria submitted to Biomedical Journals" established by the International Committee of Medical Journal Editors (October 2008); ohe standardized criteria of Medico Research Chronicles and its relevant specifications are summarized below.

Language of Manuscript

Medico Research Chronicles, accepts manuscripts written in American English.

Copies of any permission(s)

It is the responsibility of authors/ contributors to obtain permissions for reproducing any copyrighted material. A copy of the permission obtained must accompany the manuscript. Copies of any and all published articles or other manuscripts in preparation or submitted elsewhere that are related to the manuscript must also accompany the manuscript.

Types of Manuscripts

Original articles: They include randomized controlled trials, intervention tests, screening and diagnostic test tests, outcome studies, cost-effectiveness research, high response rate case-control collection, and surveys. The text of the original articles will be divided into parts with captions Abstract, Key-words, Introduction, Material and Methods, Results, Discussion, References, Tables and Figure legends; of up to 3000 words (excluding abstracts, references and tables).

Introduction: State the purpose and summarize the rationale for the study or observation.

Materials and 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 of 1975, as revised in 2000 (available at 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 anaesthetics and analgesics used should be clearly stated. The ethical standards of experiments must be in accordance with the guidelines provided by the CPCSEA and 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 article 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.

Study design:

Selection and Description of Participants: 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. Technical information: 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 (

Meta-analyses of observational studies in epidemiology


Statistics: Wherever practicable, evaluate and present results with acceptable measurement error or uncertainty measures (such as confidence intervals). Authors will record observational losses (for example, dropouts from a clinical trial). In the section Results, when data is presented, describe the statistical methods used to analyze them. Avoid non-technical uses of technical terms in statistics, such as 'random' (which implies a randomizing device), 'normal', 'significant', 'correlations', and 'sample'. Define statistical terms, abbreviations, and most symbols. Specify the computer software used. Use upper italics (P 0.048). For all P values include the exact value and not less than 0.05 or 0.001. 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 illustrations, giving the main or most important findings first. Do not repeat in the text all the data in the tables or illustrations; emphasize or summarize only important observations. Extra- or supplementary materials and technical detail can be placed in an appendix where it will be accessible but will not interrupt the flow of the text; alternatively, it can be published only in the electronic version of the journal.

When data is presented in the Results section, provide numerical results not only as derivatives (e.g., percentages) but also as the absolute numbers from which the derivatives were determined, and define the statistical methods used to evaluate them. Restrict tables and figures to those needed to illustrate the paper's case and determine its support. Using graphs as an alternative to multi-entry tables; don't repeat data in graphs and tables. Analysis of the data by factors such as age and sex should be used where scientifically relevant.

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 (is there a systematic review to refer to, if not, could one be reasonably done here and now?, what this study adds to the available evidence, effects on patient care and health policy, possible mechanisms); 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.

Review Articles: Those articles are supposed to be written by authors that have done extensive research on the topic or are considered experts in the area. The manuscript will contain a short description of the research undertaken by the contributor(s) in the field of study.

The prescribed word count is up to 3000 words excluding tables, references and abstract. The manuscript may have about 90 references. The manuscript should have an unstructured Abstract (250 words) representing an accurate summary of the article. The section titles would depend upon the topic reviewed. Authors submitting review article should include a section describing the methods used for locating, selecting, extracting, and synthesizing data. These methods should also be summarized in the abstract.

The journal requires the reviewers to provide updates on the review subject post-publication. The update will be short, describing the developments in the field since the article was written, and should be submitted as a letter to the editor if and when there is new progress in the field.

Case reports: New, interesting and rare cases can be reported. They should be unique, describing a great diagnostic or therapeutic challenge and providing a learning point for the readers. Cases with clinical significance or implications will be given priority. These communications could be of up to 1000 words (excluding Abstract and references) and should have the following headings: Abstract (unstructured), Key-words, Introduction, Case report, Discussion, Reference, Tables and Legends in that order.

The manuscript could be of up to 1000 words (excluding references and abstract) and could be supported with up to 10 references.

Letter to the Editor: These should be short and decisive observations. They should preferably be related to articles previously published in the Journal or views expressed in the journal. They should not be preliminary observations that need a later paper for validation. The letter could have up to 500 words and 5 references. It could be generally authored by not more than four authors.

Other: Editorial, Guest Editorial, Commentary and Opinion are solicited by the editorial board.


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 with square bracket after 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. 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. 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, for other types of references such as newspaper items please refer to ICMJE Guidelines ( or
