- Short Report
Original Article: Maximum length for a Regular Article is 4,000 words of text - counting only the Introduction, Methods, Results, and Discussion. Submissions are limited to a total of 5 digital images. We recommend a limit of 20 references. The sections of an Original Article should be ordered as follows:
- Materials and Methods
- Authorship Contributions
- Disclosure of Conflicts of Interest
- Figure Legends
Any involvement of medical writers/researchers, particularly those employed or supported by the pharmaceutical industry, in the writing of an article must be clearly defined and disclosed in the Authorship and/or the Acknowledgements section(s) as appropriate. This type of involvement must also be disclosed to the Editor-in-Chief in the Cover Letter. Please ensure that a ‘Declaration of Conflicting Interests’ statement is included at the end of your manuscript, after any acknowledgements and prior to the references. If no conflict exists, please state that ‘The Author(s) declare(s) that there is no conflict of interest’.
Letter to Editor
A letter to the Editor is a brief communication that either addresses the contents of a published article, or is a correspondence unrelated to a specific article. Its purpose is to make corrections, provide alternative viewpoints, or offer counter arguments. Avoid logical fallacies and ad hominem attacks. Letters to the Editor must be written in a professional tone and can include references to support all claims if appropriate
Editorials are written by associate editors or commissioned. They reflect on issues of general interest to coagulation, bleeding disorders, or on issues of special interest to Hematology. They should be written in a crisp, lively style. They should have a maximum of 800 words, and not more than 5 references
These are studies that fall short of the criteria for full research papers (e.g., new results with a relatively simple experimental design and without confirmatory follow-up work). They should be written as an unstructured abstract, one paragraph, max. 200 words; Main body of text (excluding abstract, tables/figures, and references) not to exceed 1,000 words; Max 2 tables or figures; Max 20 references
The number of authors for a case report should be limited to three to five, of which at least one must have been involved in the patient's care. Case reports should be short and focused, with a limited number of figures and references. The structure of a case report usually should comprise a short unstructured abstract, brief introduction, report of the case, and discussion. The maximum number of references is 15.
Short reports should have the same format as original articles, but should not exceed 1200 words, and contain a maximum of one table/figure. Abstracts of short reports should not be structured, and should be no longer than 100 words. The maximum number of references is 10.
Please make sure your title page contains the following information.
- Title (The title should be concise and informative).
- Author List and Affiliations: Authors' full first and last names must be provided. The initials of any middle names can be added. The PubMed/MEDLINE standard format is used for affiliations: complete address information including city, zip code, state/province, and country. At least one author should be designated as corresponding author, and his or her email address and other details should be included at the end of the affiliation section.
- Abstract (please provide an abstract of 150 to 250 words. It must be structured in: Aims, Materials and Methods, Results, Discussion. The abstract should not contain references)
- Keywords: Please provide 4 to 6 keywords which can be used for indexing purposes.
All contributors who do not meet the criteria for authorship should be listed in an 'Acknowledgements' section. Additionally, if the article has been submitted on behalf of a consortium, all author names and affiliations should be listed at the end of the article in the Acknowledgements section. Authors should also disclose whether they had any writing assistance.
The style of references conforms to the guidelines set forth by the AMA Manual of Style. For Specific examples and information regarding references, see the manual or visit online: http://www.amamanualofstyle.com. EndNote users can access a direct download of the JAMA style at Medicine's Editorial Manager site. Authors using other forms of reference management software should use JAMA style.
All references cited in the text must be both listed and cited by the reference number (footnotes are not accepted).
Each reference should be cited in the text in consecutive numerical order by means of superscript arabic numerals. Use superscript numerals outside periods and commas, inside colons and semicolons. When more than 2 references are cited at a given place in the manuscript, use hyphens to join the first and last numbers of a closed series; use commas without space to separate other parts of a multiple citation (eg, As reported previously,1,3-8,19...The derived data were as follows 3,4,12:)
References should be numbered consecutively in the order in which they are cited in the text.
References in tables and in figure legends must appear in the reference page(s).
In listed references, use the author's surname followed by initials without periods. (eg, Black AB)
For references with 6 or fewer authors, list all authors. For references with more than 6 authors, list the first 3 authors followed by "et al."
1 author Black A.
2 authors Black A, Green B.
6 authors Black A, Green B, White C, Grey D, Rose E, Orange F.
6 authors Black A, Green B, White C, et al.
Full-page ranges should be given in expanded form (eg, 426–429, not 426–9).
Use the covering letter to explain why your paper should be published in the OJHM rather than elsewhere (eg, a specialty journal).
