The introduction should be concise, one-page section describing the purpose and hypotheses of the study. Briefly describe what is already known on the subject and what this study aims to accomplish. Point out why this study is needed and where it differs from the published literature. Avoid a long general discussion on the subject. State your main hypotheses at the end.
• Describe the type of the study (retrospective, prospective randomized ect.) and give information on the design, timeline, primary and secondary outcome measurements.
• Clearly describe your sample, state sample size, inclusion and exclusion criteria. Sample size calculation needs to be presented in all clinical studies. Basic demographic data of the patients such as age, gender, BMI ect. can be given here.
• Use a CONSORT Flow Diagram (http://www.consort-statement.org/consort-statement/flow-diagram) to describe patient enrollment, intervention allocation, follow-up, and data analysis.
• The methods need to be clearly described to allow for other researchers to reproduce your results. Give a detailed description of the tests and experiments used for experimental studies. A thorough description of treatment and surgical techniques are needed for novel therapies. The description can be shorter if standard techniques are used. Define the primary and secondary outcome measures, describe when and how these were measured.
• ICC values for intra and inter-observer reliability should be reported if relevant.
• Describe informed consent procedure for clinical trials, even if not needed (such as retrospective database analyses). Give information on the local ethical committee or institutional review board approval.
• Clearly describe statistical methods, including the tests used parametric and non-parametric variables. Define the level of statistical significance (usually p<0.05)
• Clearly report your results in the main body of the text, tables and figures.
• Follow the sequence & structure of the materials & methods section to report your results in an orderly fashion.
• Do not repeat data already in the tables and figures again in the main body of the text. Use the text to highlight your main outcomes, leave most of the numerical data for the tables and figures.
• Do not comment on your results or use references in the results section.
• Start the discussion with your most important findings. Point out the novelty and clinical relevance of your findings.
• Avoid a lengthy background discussion on historical perspective and repetition of general knowledge. Do not repeat your results. Discuss only the literature relevant to your findings, describe how your study differs from what has already been done.
• Add a final paragraph on the strengths and limitations of your study. Point out what can be improved and areas for future research.
• Use two sentences to underline your main findings and conclusions. Describe the clinical relevance of your work.
• Base your conclusions on your findings. Avoid conclusions such as “Further studies are needed…”; and uncertain terms such as “seems to be …” “we hope that..”
• The references should be numbered in the order of appearance in the text. The references should appear in square brackets at the end of the relevant sentence in the main manuscript, such as [1,2]. Do not use superscript.
• Only articles, clinical trial registration records and abstracts that have been published can be used as references. Unpublished abstracts, data and personal communications should not be included in the reference list. These may be used in the main body of the text and described as unpublished data or personal communications.
• All web links and URLs should have a reference number and included in the reference list with the URL address and date accessed.
• Index Medicus/MEDLINE journal abbreviations should be used for journals in this database. Full name of the journals should be provided for journals not in the database.
• GRJ uses the Summary(text) format of PubMed for references. The first 5 authors should be listed, “et al.” can be used after the first 5 authors. Digital object identifier (doi) numbers are needed only for electronic and pre-print articles. Do not include doi numbers for published articles.
