   References Top


  • Only papers closely related to the author's work should be referenced; 4 exhaustive lists should be avoided. Verify all references for completeness and accuracy, and format references as a plain, unstructured list.
  • We recommend the use of a tool such as EndNote or Reference Manager for reference management and formatting.
EndNote reference styles can be searched for here: Reference Manager reference styles can be searched for here:
  • Accuracy of reference data is the responsibility of the author.
  • Verify all references against original sources.
  • List all authors for each reference; do not use “et al.”
Example of a good reference:
1. Smith HJ, Allen S, Yu W, Fard S. This is the title. Circulation. 2004; 104:276-308. For further examples, see the 'Uniform Requirements for Manuscripts Submitted to Biomedical Journals' at
  • Cite references in numeric order according to first mention in the text. In the text, ensure accuracy of spelling and details of publication, i.e., the text citation should match the reference information.
  • Personal communications, unpublished observations, and submitted manuscripts are not legitimate references. They must be cited in the text only (not in the reference list) as follows: author name, degree(s) held, unpublished data, year.
  • Abstracts may be cited only if they are the sole source and must be identified in the reference as “Abstract.”
  • References must be from a full length publication in a peer reviewed journal.
  • “In press” citations must have been accepted for publication and the name of the journal or book publisher must be included.
   Figures Top


  • Figure parts should be clearly labeled. Letters must be uniform in size and style within each figure, and when possible, between figures. (The font size must be 8 point or higher.)
  • Avoid headings on the figure. Heading information should appear in the figure legend.
  • Line art should not contain hairlines, which are hard to reproduce.
  • Supply a scale bar with photomicrographs.
  • Provide double-spaced copy for figure legends on a separate page.
  • Symbols and abbreviations must be defined in the figure or its legend.
  • Limit white space between the panel and panel label.
  • Figures should be sized as close as possible to their final print size. Please note that very few figures qualify for a 2-column format.
   Tables Top


  • Tables should be kept to a minimum and contain only essential data. Verify
  • nformation for accuracy and consistency with the manuscript's text.
  • The title (legend) of the table should contain only minimal text. Any other information, such as definitions of abbreviations, probability statistics, etc., should be in the table footnote; if symbols are necessary, they should be the same as given for the authors' details above. Headings and columns should be laid out clearly; avoid use of sub-headings. Avoid wordy, over-full tables. Any blank cells should have a dash.
  • Begin each table on a separate page, double-spaced. Please remember that tables prepared with Excel are not accepted unless embedded within your text document.
  • The table number should be arabic, followed by a period and brief title.
  • Use same size type as in text.
  • Indicate footnotes in this order: *, †, ‡, §, ||, #, ** etc.
  • Do not use vertical lines between columns. Use horizontal lines above and below the column headings and at the bottom of the table only. Use extra space to 6 delineate sections within the table. 
   Ethical Policy Top

Manuscripts are considered on the understanding that they contain original material, which the manuscript and material within the manuscript have not been published and are not being considered for publication elsewhere in whole or in part in any language, including publicly accessible web sites or e-print servers, except as an abstract. The authors also certify that any and all other work in preparation, submitted, in press, or published that is potentially overlapping either in the actual data presented or in the conceptual approach is enclosed along with the original submission. Any material within the manuscript that has appeared elsewhere must be cross-referenced and permission to use or adapt the material must be received, in writing from the copyright holder. 

   Guidelines for Clinical Trials Top


In accordance with the Clinical Trial Registration Statement from the International Committee of Medical Journal Editors (Circulation. 2005;111:1337) and (, all clinical trials in Circulation must be registered in a public trials registry at or before the onset of participant enrollment. This requirement applies to all clinical trials that begin enrollment after July 1, 2005.
Research is considered to be a clinical trial if it involves prospective assignment of human subjects to an intervention or comparison group to study the relation between a health-related intervention and a health outcome.
The registry must be accessible to the public at no charge, searchable, open to all prospective registrants, and managed by a not-for-profit organization. The registry must include the following information: a unique identifying number, a statement of the intervention(s), study hypothesis, definition of primary and secondary outcome measurements, eligibility criteria, target number of subjects, funding source, contact information for the principal investigator, and key dates (registration date, start date, and completion date). The registry sponsored by the United States National Library of Medicine ( meets these requirements and is recommended by the editors. Other registries are acceptable if they meet these requirements. In addition to, the following registries are recommended by the ICMJE: 1) 2) 3) 4) In accordance with the ICMJE’s recommendation, we will also accept registration of clinical trials in any of the primary registers that participate in the World Health Organization’s International Clinical Trial Registry Platform. Primary registers are WHO selected registers managed by not-for-profit entities that will accept registrations for any interventional trials, delete duplicate entries from their own register, and provide data directly to the WHO. Please note that registration in any WHO partner registers is insufficient. The authors will be requested to provide the exact URL and unique identification number for the 7 trial registration at the time of submission. Since this information will be published in a footnote on the first page of the article, we ask that you include the URL and identification number on the title page of your manuscript.
Clinical trial reports should also comply with the Consolidated Standards of Reporting Trials (CONSORT) and include a flow diagram presenting the enrollment, intervention allocation, follow-up, and data analysis with number of subjects for each ( Please also refer specifically to the CONSORT Checklist of items to include when reporting a randomized clinical trial.
Results posted in the same clinical trials registry in which the primary registration resides will not be considered prior publication if they are presented in the form of a brief abstract (<500 words or less) or a table.

   Guidelines for Human Phenotype-Genotype Association or Linkage Studies Top
Reporting issues.
  1. Report process for selecting genes and SNPs.
  2. Report Hardy-Weinberg statistics or p-values and method of calculating same.
  3. Refer to existing public domain websites for the Human Gene Ontology name and the rs number for SNPs.
  5. Describe genotyping methods. If numerous primers have been used, please include them in an online supplement.
  6. False positive and false negative concerns.
Given well-described problems with both false positive and false negative associations, phenotype-genotype association studies should meet some or all of the criteria below: 8
  1. Phenotype is clearly defined, is heritable, and if a quantitative phenotype is reported, reproducibility data are provided.
  2. The sample size is adequate to detect a SNP or haplotype with a modest effect. For genotype-trait associations, provide an estimate of the effect size that could be detected with power 0.80 or higher with the allele frequency and sample size reported.ı
  3. Since multiple statistical testing methods are frequently used in genotypingphenotyping studies, please include specifics of the primary model(s) tested. Nonessential secondary models may be published as electronic data supplements. Clinically relevant confounders should be included in multivariable models or residuals.
  4. Review criteria for human linkage studies.
Manuscripts should include the following:
  1. Identifying plausible candidate genes under the linkage peak.
  2. Follow-up fine mapping to narrow the region of linkage, &/or genotyping some of the candidate genes under the linkage peak.
  3. Replication data from another sample.
