Article Types

When preparing the manuscript for PAEDIATRIA CROATICA, authors must first determine the article type, and then select the appropriate manuscript preparation instructions from the types listed below. Also, become familiar with the journal style and correct preparation of figures, tables, and multimedia.

  • Original Articles

    • Maximum text length: 3000 words
    • Tables and figures: max 5
    • References: max 40
    • Original articles are research contributions that aim to change clinical practice or the understanding of a disease process. They include, but are not limited to clinical trials, interventional studies, cohort studies, case-control studies, epidemiologic assessments, and surveys.
    • Components of an Original Article include:
      • Structured Abstract. Authors must supply up to three brief points "What is already known on this topic", and up to three brief points stating "What this paper adds?".
      • Introduction. A one- to two-paragraph long introduction outlining the wider context that generated the study and the hypothesis.
      • Patients and Methods. Section detailing inclusion criteria and study design to ensure reproducibility of the research.
      • Results: This section should give specific answers to the aims or questions stated in the introduction. Results should be clear and concise. The order of presentation of results should parallel the order of the methods section. The data presented in the tables or figures should not be repeated in the text. Graphs should be used as an alternative to tables with many entries; do not present the same data in duplicate (e.g., in both graphs and tables).
      • Discussion. An expanded discussion highlighting antecedent literature on the topic and how the current study changes the perception of the current knowledge on the subject.
      • Conclusion. A concluding paragraph presenting the impact of the study and possible new research on the subject.
  • Review Articles
    • Maximum text length: 5000 words
    • Tables and figures: max 5
    • References: max 50
    • Review Articles combine and/or summarize data from the knowledge base of a topic. These articles can include systematic reviews and meta-analyses. Reports of systematic reviews and meta-analyses should use the PRISMA statement as a guide, and include a completed PRISMA checklist and flow diagram to accompany the main text. Blank templates of the checklist and flow diagram can be downloaded from the http://www.prisma-statement.org/usage.htm. When writing review article, it is recommended to use a Structured Abstract with following headings: Context, Objective, Data Sources, Study Selection, Data Extraction, Results, and Conclusions.
    • Authors considering the submission of uninvited reviews should contact the Editor-in-Chief in advance to determine whether the topic that they propose is of current potential interest to the PAEDIATRIA CROATICA. 
  • Clinical and Laboratory Observations (CLOs)
    • Maximum text length: 2000 words 
    • Tables and figures: max 4
    • References: max 20
    • CLOs are: (1) small series of diagnostic or therapeutic interventions; or (2) brief, focused studies related to a topic of interest to pediatricians. Please note that CLOs are not designed to present information that is generally available in textbooks, even if the reported entity is novel. CLOs are designed to provide readers with new information and stimulate new approaches to diagnosis, clinical management, or research.
    • Structured Abstract: Authors must supply up to three brief points "What is already known on this topic", and up to three brief points stating "What this paper adds?".
    • Introduction: A one- -paragraph short introduction outlining the background and outlining the aims of the study.
    • Patients and Methods: Section detailing inclusion criteria and study design to ensure reproducibility of the research.
    • Results: This section should give specific answers to the aims or questions stated in the introduction. Results should be clear and concise. The order of presentation of results should parallel the order of the methods section. The data presented in the tables or figures should not be repeated in the text. Graphs should be used as an alternative to tables with many entries; do not present the same data in duplicate (e.g., in both graphs and tables). Exact P-values should be provided for all tested differences (e.g., write P=0.048 instead of P<0.05) rounded to three decimal places.
    • Discussion:  A short discussion highlighting antecedent literature on the topic and how the current study changes the perception of the current knowledge on the subject.
    • Conclusion: A concluding paragraph presenting the impact of the study and possible new research on the subject.

  • Case Reports
    • Maximum text length: 1800 words
    • Tables and figures: max 4
    • References: max 20
    • Case Report articles are descriptions of a case or small number of cases revealing novel and important insights into a condition's pathogenesis, presentation, and/or management in order to expand differential diagnosis and improve patient care. Case Report articles should be structured as follows:

      • Abstract. An unstructured or structured abstract that summarizes the case(s).
      • Introduction. A brief introduction.
      • Patient Presentation. A case report section that details patient presentation, initial diagnosis, and outcome.
      • Discussion. A discussion section including a brief review of the relevant literature and how this case brings new understanding to the disease process.
  • Research Letter
    • Maximum text length: 600 words
    • Tables and figures: max 2
    • References: max 6
    • Authors: no more than 5
    • These are very brief reports offered in a letter format reporting a clinical or laboratory observation that adds to the scientific knowledge of the condition. As in all letters, the manuscripts are not subdivided into sections nor do they include an abstract. Key words are required for indexing purposes.
  • Commentaries
    • Maximum text length: 800 words
    • Tables and figures: NO tables/figures
    • References: max 5
    • Authors: no more than 3
    • Commentaries are opinion pieces consisting of a main point and supporting discussion. They may address virtually any important general issues or controversies in the field of pediatrics. These contributions usually pertain to and are published concurrently with a specific article. Commentaries should be well focused, scholarly and clearly presented, and serve to launch a broader discussion of a topic.
      Authors who wish to propose a Commentary should e-mail a proposal letter and outline to the Editor-in-Chief for approval before submitting the full manuscript.
  • Letters to the Editor
    • Maximum text length: 300 words
    • Tables/figures: NO tables/figures
    • References: max 5
    • Authors: no more than 3
    • Letters to the Editor may be submitted in response to work that has been published in the PAEDIATRIA CROATICA within the past year or to related topics. Letters should be short commentaries related to specific points of agreement or disagreement with the published work. Letters are not intended for presentation of original data unrelated to a published article. Letters must not duplicate other material published or submitted for publication and should not include unpublished data.
      Letters will be published at the discretion of the Editors and are subject to abridgement and editing for style and content.
  • Clinical Practice Guidelines - Clinical Practice Guidelines identify, summarize and evaluate the highest quality evidence and most current evidence based data about prevention, diagnosis, prognosis and treatment, including dosage of medications, risk/benefit and cost-effectiveness.
    In order to guide decisions and criteria regarding diagnosis, management and treatment in specific diseases, PAEDIATRIA CROATICA publishes Clinical Practice Guidelines. These recommendations are developed by medical specialty societies, professional associations, public and private organizations, government agencies, and health care organizations.
  • Society News
    The Society News keeps the readership informed about past conferences and upcoming events and announcements related to clinical and translational research. If you have an event or announcement that you would like us to include, please contact the secretary of Paediatria Croatica.
