Abstract

The abstract of the manuscript should not exceed 250 words and must be structured into separate sections:

Introduction, the context and purpose of the study. Methods, how the study was performed and statistical tests used. Results, the main findings. Conclusions, brief summary and potential implications. Minimize the use of abbreviations and do not cite references in the abstract. Trial registration (if applicable), if your guideline reports the results of a controlled health care intervention, please list your trial registry, along with the unique identifying number (e.g. Trial registration: Current Controlled Trials ISRCTN73824458).

Keywords

Three (3) to five (5) keywords representing the main content of the article.

Introduction

The introduction should be written in a way that is accessible to researchers without specialist knowledge in that area and must clearly state - and, if helpful, illustrate - the background to the research and its aims. Reports of clinical research should, where appropriate, include a summary of a search of the literature to indicate why this study was necessary and what it aimed to contribute to the field.

Materials and methods

The methods section should include the design of the study, the setting, the type of participants or materials involved, a clear description of all procedures, interventions and comparisons, and the type of analysis used, including a power calculation if appropriate. Generic drug names should generally be used.

The Accession Numbers of any nucleic acid sequences, protein sequences or atomic coordinates cited in the manuscript should be provided, in square brackets and include the corresponding database name; for example, [EMBL:AB026295, EMBL:AC137000, DDBJ:AE000812, GenBank:U49845, PDB:1BFM, Swiss-Prot:Q96KQ7, PIR:S66116].

Results

Results of statistical analysis should include, where appropriate, relative and absolute risks or risk reductions, and confidence intervals.

Discussion

Discussion should not be a repetition of the results. Authors should discuss implications of the findings.

Conclusions

This should state clearly the main conclusions of the research and give a clear explanation of their importance and relevance. Summary illustrations may be included.
