Ethical Policy

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

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 (http://www.clinicaltrials.gov) meets these requirements and is recommended by the editors. Other registries are acceptable if they meet these requirements. In addition to www.clinicaltrials.gov, the following registries are recommended by the ICMJE: 1) http://isrctn.org 2) www.umin.ac.jp/ctr/index/htm 3) www.actr.org.au 4) www.trialregister.nl 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 (http://www.consort-statement.org/?o=1011). 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

Reporting issues.
http://www.gene.ucl.ac.uk/nomenclature/
http://www.ncbi.nlm.nih.gov/projects/SNP/
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Snp

  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.
  4. Describe genotyping methods. If numerous primers have been used, please include them in an online supplement.
  5. 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.
  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.

The Editorial Process
The manuscript will be reviewed for possible publication with the understanding that it is being submitted to Journal of Cardiovascular Disease Research alone at that point in time and has not been published anywhere, simultaneously submitted, or already accepted for publication elsewhere. The journal expects that authors would authorize one of them to correspond with the Journal for all matters related to the manuscript. All manuscripts received are duly acknowledged. On submission, editors review all submitted manuscripts initially for suitability for formal review. Manuscripts with insufficient originality, serious scientific or technical flaws, or lack of a significant message are rejected before proceeding for formal peer-review. Manuscripts that are unlikely to be of interest to the Journal of Cardiovascular Disease Research readers are also liable to be rejected at this stage itself.
Manuscripts that are found suitable for publication in Journal of Cardiovascular Disease Research are sent to two or more expert reviewers. During submission, the contributor is requested to provide names of two or three qualified reviewers who have had experience in the subject of the submitted manuscript, but this is not mandatory. The reviewers should not be affiliated with the same institutes as the contributor/s. However, the selection of these reviewers is at the sole discretion of the editor. The journal follows a double-blind review process, wherein the reviewers and authors are unaware of each other’s identity. Every manuscript is also assigned to a member of the editorial team, who based on the comments from the reviewers takes a final decision on the manuscript. The comments and suggestions (acceptance/ rejection/ amendments in manuscript) received from reviewers are conveyed to the corresponding author. If required, the author is requested to provide a point by point response to reviewers’ comments and submit a revised version of the manuscript. This process is repeated till reviewers and editors are satisfied with the manuscript.
Manuscripts accepted for publication are copy edited for grammar, punctuation, print style, and format. Page proofs are sent to the corresponding author. The corresponding author is expected to return the corrected proofs within three days. It may not be possible to incorporate corrections received after that period. The whole process of submission of the manuscript to final decision and sending and receiving proofs is completed online. To achieve faster and greater dissemination of knowledge and information, the journal publishes articles online as ‘Articles In Press’ immediately on acceptance.

Authorship criteria
Authorship credit should be based only on substantial contributions to each of the three components mentioned below:
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 solely in the acquisition of funding or the collection of data does not justify authorship. General supervision of the research group is not sufficient for authorship. Each contributor should have participated sufficiently in the work to take public responsibility for appropriate portions of the content of the manuscript. The order of naming the contributors should be based on the relative contribution of the contributor towards the study and writing the manuscript. Once submitted the order cannot be changed without written consent of all the contributors. The journal prescribes a maximum number of authors for manuscripts depending upon the type of manuscript, its scope and number of institutions involved (vide infra). The authors should provide a justification, if the number of authors exceeds these limits.
Contribution Details
Contributors should provide a description of contributions made by each of them towards the manuscript. Description should be divided in following categories, as applicable: concept, design, definition of intellectual content, literature search, clinical studies, experimental studies, data acquisition, data analysis, statistical analysis, manuscript preparation, manuscript editing and manuscript review. Authors' contributions will be printed along with the article. One or more author should take responsibility for the integrity of the work as a whole from inception to published article and should be designated as 'guarantor'.
Conflicts of Interest/ Competing Interests
All authors must disclose any and all conflicts of interest they may have with publication of the manuscript or an institution or product that is mentioned in the manuscript and/or is important to the outcome of the study presented.

Correct / Acceptable Format
Noonan Syndrome is a relatively common disorder, seen in 1 in every 1000 to 2500 live births.1 It is an autosomal dominant disease with variable expressivity and no sex or race predilection.2-4 Typically, it is easy to observe, as there are several distinct physical features associated with the disease. These features are similar to Turner syndrome, including shortened stature and neck webbing.5 However, there are some facial dimorphisms unique to Noonan Syndrome, such as a deep philtrum and low-set ears.6,7
