Author Guidelines

General Requirement

The manuscript submitted to Berkala Kesehatan Klinik (BKK) has never been published and is not simultaneously submitted to another scientific journal for publication. Submission of a manuscript implies that the work has not been published before (except as part of a thesis, report, or abstract); that it is not under consideration elsewhere; and that its publication has been approved by all co-authors. The first author must ensure that all co-authors have read and agreed to the manuscript’s content.

Research manuscripts involving human subjects or experimental animals must include ethical clearance from a Health Research Ethics Committee, proven by the attached approval letter. Manuscripts written according to the BKK template (Research Article, Case Report, Review Article, or Editorial) will be further processed.

Author Statement

Before the article is published, the author statement form must be submitted online. This form includes declarations of originality, confirmation that the work is not in process or published elsewhere, author contributions and agreements, absence of conflicts of interest, and ethical approval of the research project by a properly constituted research ethics committee. The statement form can be downloaded from the BKK journal website.

Explanation

Title
The title is written in English, concise and clear, no more than 14 words, and must reflect the results. Each initial letter in the title must be capitalized except conjunctions. Abbreviations should be avoided, except for common terminology.

Authors
All author names must be written in full, without academic titles or abbreviations. The maximum number of authors is five; if more, “et al.” may be used. Each author must include full institutional affiliation (department, institution, official address). The corresponding author is advised to provide an email address to facilitate communication.

Abstract
Abstracts are written in English in an unstructured format. For research articles, the abstract should not exceed 200 words and must cover background, objectives, methods, results, and conclusions. For case reports, the abstract should be a maximum of 150 words, summarizing the background, main points of the case, and the key lessons learned. For review articles, the abstract should summarize the purpose, scope, and conclusions in a maximum of 200 words. No references or suggestions are included in the abstract. Keywords consist of 3–5 words separated by a semicolon (;).

Introduction
The introduction provides justification for the importance of the study. Novelty compared to previous research or knowledge must be explicitly shown. The last paragraph should state the study objectives or hypotheses. For case reports, the introduction briefly explains the relevance and significance of the case supported by recent literature.

Materials and Methods
This section describes study design, sample size, criteria and sampling methods, instruments, and procedures of data collection and analysis. For clinical or experimental studies, interventions and procedures must be described. Ethical approval must be mentioned for studies involving human or animal subjects.

Results
Results should present research findings in tables, graphs, or figures, accompanied by a brief explanatory text. Data should not be repeated in narration and visuals simultaneously. The presentation must follow the objectives or hypotheses of the study. No citations are included in this section.

Case Presentation
Case descriptions are presented chronologically, including history, examination, investigation results, management, and follow-up. Confidentiality must be maintained by excluding identifiable information. Clinical photographs or radiological images may be used, provided they are anonymized.

Discussion
Discussion compares study results with previous literature, highlighting similarities, differences, uniqueness, and implications for clinical practice. For case reports, the discussion emphasizes added value, clinical lessons, and novelty compared with existing reports. Limitations of the study or case should be acknowledged.

Conclusion
The conclusion should be concise, written in one or two paragraphs, and directly address the objectives or hypothesis. It should not contain statistical data or recommendations. In case reports, the conclusion reaffirms the uniqueness and lessons learned.

Acknowledgement
Acknowledgements are optional and limited to individuals or institutions that provided professional, technical, financial, or material support.

Conflict of Interest
Authors must disclose all potential conflicts of interest, whether financial or non-financial, academic, institutional, or personal, that could influence the research or its interpretation.

References
References should primarily consist of recent (last 10 years) journal articles, with at least 80% from scientific journals and 60% from reputable international sources. A minimum of 20 references is required for research articles and case reports. References should follow the Vancouver style, cited in superscript numbers, and arranged in the order of appearance in the text.
