The Turkish Journal of Hematology accepts invited review  articles, research articles, brief reports, letters to the editor, and  hematological images that are relevant to the scope of hematology, on the  condition that they have not been previously published elsewhere. Basic science  manuscripts, such as randomized, cohort, cross-sectional, and case control  studies, are given preference. Articles consisting solely of computational analyses and meta-analyses without validation with primary biological samples (blood, bone marrow, stem cells) are not within the scope of this journal. All manuscripts are subject to editorial  revision to ensure they conform to the style adopted by the journal. The reviewing system is double-blind.
  
  Manuscripts should be prepared according to ICMJE  guidelines. Original manuscripts require a structured  abstract. Label each section of the structured abstract with the appropriate  subheading (Objective, Materials and Methods, Results, and Conclusion). Letters  to the editor do not require an abstract. Research or project support should be  acknowledged as a footnote on the title page. Technical and other assistance  should be provided on the title page. 
  
  Submissions and publication are free of charge.
  
  Original  Manuscripts 
  
  Title Page  
  Title: The title should provide important information  regarding the manuscript’s content. The title must specify that the study is a  cohort study, cross-sectional study, case control study, or randomized study  (i.e. Cao GY, Li KX, Jin PF, Yue XY, Yang C, Hu X. Comparative bioavailability  of ferrous succinate tablet formulations without correction for baseline  circadian changes in iron concentration in healthy Chinese male subjects: A  single-dose, randomized, 2-period crossover study. Clin Ther. 2011; 33:  2054-2059).
  
  The title page should include the authors’ names,  degrees, and institutional/professional affiliations and a short title,  abbreviations, keywords, financial disclosure statement, and conflict of  interest statement. If a manuscript includes authors from more than one  institution, each author’s name should be followed by a superscript number that  corresponds to their institution, which is listed separately. Please provide  contact information for the corresponding author, including name, e-mail  address, and telephone and fax numbers.
  
  Important Notice:  The title page should be submitted separately.
  Running Head: The running head should not be more than 40 characters,  including spaces, and should be located at the bottom of the title page.
  
  Word Count: The word count of a manuscript, excluding the abstract, acknowledgments, figure and table legends, and references, should not exceed 2500 words. The word count of an abstract should not exceed 300 words.
  
  Conflict-of-Interest Statement: To prevent  potential conflicts of interest from being overlooked, this statement must be  included in each manuscript. In case there are conflicts of interest, every  author should complete the ICMJE general declaration form.
  
  Abstract and Keywords: The second page should include an  abstract that does not exceed 300 words. For manuscripts sent by authors in  Türkiye, a title and abstract in Turkish are also required. As most readers read  the abstract first, it is critically important. Moreover, as various electronic  databases integrate only abstracts into their index, important findings should  be presented in the abstract.  
  
  Objective: The abstract should state the objective (the purpose of  the study and hypothesis) and summarize the rationale for the study. 
  
  Materials and Methods: Important methods should be  written respectively.
  
  Results: Important findings and results should be provided here. 
  
  Conclusion: The study’s new and important findings should be  highlighted and interpreted.
  
	Other types of manuscripts, such as reviews, perspectives, and editorials, will be published according to uniform requirements. Provide 3-10 keywords below the abstract to assist indexers. Use terms from the
	Index Medicus Medical Subject Headings List (https://www.nlm.nih.gov/mesh/meshhome.html). For randomized studies, a CONSORT abstract should be provided (http://www.consort-statement.org/).
  
  
  Introduction: The introduction should include an overview of the  relevant literature presented in summary form (one page), and the issues that remain interesting, unique, problematic, relevant, or unknown about the topic must be  specified. The introduction should conclude with the rationale for the study,  its design, and its objective(s).
  
  Materials and Methods: Clearly describe the selection of  observational or experimental participants, such as patients, laboratory  animals, and controls, including inclusion and exclusion criteria and a  description of the source population. Identify the methods and procedures in  sufficient detail to allow other researchers to reproduce your results. Provide  references to established methods (including statistical methods), provide  references to brief modified methods, and provide the rationale for using them  and an evaluation of their limitations. Identify all drugs and chemicals used,  including generic names, doses, and routes of administration. The section should include only information that was available at the time the plan or protocol for the study was devised (https://www.strobe-statement.org/fileadmin/Strobe/uploads/checklists/STROBE_checklist_v4_combined.pdf).
  
  Statistics: Describe the statistical methods used in enough detail  to enable a knowledgeable reader with access to the original data to verify the  reported results. Statistically important data should be given in the text, tables, and figures. Provide details about randomization, describe treatment  complications, provide the number of observations, and specify all computer  programs used. 
  
  Results: Present your results in logical sequence in the text, tables, and figures. Do not present all the data provided in the tables and/or figures in the text; emphasize and/or summarize only important findings, results, and observations in the text. For clinical studies provide the number of samples, cases, and controls included in the study. Discrepancies between the planned number and obtained number of participants should be explained. Comparisons and statistically important values (i.e. p value and confidence interval) should be provided.
  
  Discussion: This section should include a discussion of the data.  New and important findings/results and the conclusions they lead to should be  emphasized. Link the conclusions with the goals of the study, but avoid  unqualified statements and conclusions not completely supported by the data. Do  not repeat the findings/results in detail; important findings/results should be  compared with those of similar studies in the literature, along with a  summarization. In other words, similarities or differences in the obtained  findings/results with those previously reported should be discussed. 
  
  Study Limitations: Limitations of the study should be  detailed. In addition, an evaluation of the implications of the obtained  findings/results for future research should be outlined.  
  
  Conclusion: The conclusion of the study should be highlighted.
  
  References
  Cite references in the text, tables, and figures with  numbers in square brackets. Number references consecutively according to the order  in which they first appear in the text. Journal titles should be abbreviated  according to the style used in Index Medicus (consult List of Journals Indexed  in Index Medicus). Include among the references any paper accepted for publication but not yet published, designating the journal followed by "in press."

  Invited Review Articles 
  Abstract length: Not to exceed 300 words. 
  Article length: Not to exceed 4000 words.
  Review articles  should not include more than 100 references. Reviews should include a  conclusion, in which a new hypothesis or study about the subject may be  posited. Do not publish methods for literature search or level of evidence.  Authors who submit review articles should have already published research articles on the relevant subject. The study’s new and important findings should  be highlighted and interpreted in the Conclusion section. There should be a  maximum of two authors for review articles.
Review articles are solicited by the Editor in Chief. Authors wishing to submit an unsolicited review article should contact the Editor in Chief prior to submission in order to screen the proposed topic for relevance and priority. 
Perspectives in Hematology
“Perspectives” are invited articles discussing significant topics relevant to hematology. They are more personal than a review article. Authors wishing to submit a Perspectives in Hematology article should contact the Editor in Chief prior to submission in order to screen the proposed topic for relevance and priority. These submissions must advance the hot subjects of experimental and/or clinical hematology beyond the articles previously published or in press in TJH. Perspective papers should meet the restrictive criteria of TJH regarding unique scientific and/or educational value, which will impact and enhance clinical hematology practice or the diagnostic understanding of blood diseases. Priority will be given to such manuscripts based upon the prominence, significance, and timeliness of the content. The submitting author must already be an expert with recognized significant published scientific experience in the specific field related to the “Perspectives” article. There should be a maximum of two authors per "Perspectives" submission.
These manuscripts are published by invitation only.
Abstract length: Not to exceed 150 words.
Article length: Not to exceed 1000 words.
References: Should not include more than 50 references.
 
 
  Images in Hematology

Online Early 
 The Turkish Journal of Hematology publishes abstracts of  accepted manuscripts online in advance of their publication. After an article has been accepted and edited, the authors have submitted the final corrections, and all changes have been applied, the article will be published online within 10 days. At that time the manuscript will receive a Digital Object  Identifier (DOI) number. Authors of  accepted manuscripts will receive electronic page proofs directly from the  printer and are responsible for proofreading and checking the entire  manuscript, including tables, figures, and references. Page proofs must be  returned within 48 hours to avoid delays in publication.
Preprint Policy 
The Turkish Journal of Hematology does not accept manuscripts that have been previously submitted to or posted on preprint servers. Any manuscript that has been made publicly available as a preprint, regardless of the platform or DOI assignment, is considered to have undergone prior publication and is therefore ineligible for submission to this journal.
To ensure adherence to this policy, authors are required to confirm during submission that their manuscript has not been deposited on any preprint server or made publicly available in any similar format prior to submission.
