    Introduction

    The information in this section should always be referenced. It should indicate the broad context and should include a brief review of the key literature related to the study.

    Methods

    This section should provide enough detail for the research to be reproduced elsewhere; protocols for new methods should be included, but well-established methodological procedures may simply be referenced. Full details of methods used should be included in the manuscript rather than in a supplementary file. If methods used are as per a published paper, the corresponding reference should be cited.

    Ethics and patient consent

    A statement on ethics committee permission and patient consent must be included in the “Methods” section (if the experiment involves the relevant content).

    Selection and description of participants

    Selection of observational or experimental participants (patients or laboratory animals, including controls) should be clearly described, including also eligibility and exclusion criteria and a description of the sources.

    · Reports of randomized clinical trials should present information on all major study elements, including the protocol, interventions(e.g. methods of randomization, concealment of allocation to treatment groups), and the method of masking (blinding).

    Statistics

    · Quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals) whenever possible.

    · Authors should report losses to observation (e.g. dropouts from a clinical trial).

    · Specify the statistical methods used to analyze data that are summarized in the “Results” section.

    · Specify the computer software used. Use upper-case italics to denotePvalues (i.e.P< 0.048).

    · 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.

    Discussion

    The discussion should be concise and tightly worded. It should include paragraphs on the generalizability, clinical relevance,strengths, and limitations of the study. And the main findings of the study should be summarized in the section.
