The Bangladesh Journal of Cardiovascular Intervention (BJCI) is committed to promoting transparency, accountability, and integrity in scholarly publishing. Authorship should accurately reflect individuals who have made substantial intellectual contributions to the research and manuscript. All authors are expected to adhere to the authorship criteria established by the International Committee of Medical Journal Editors (ICMJE) and the ethical principles endorsed by the Committee on Publication Ethics (COPE).

Authorship Criteria

BJCI follows the ICMJE Recommendations, which state that authorship should be based on all of the following four criteria:

1. Substantial contributions to the conception or design of the work, or the acquisition, analysis, or interpretation of data.
2. Drafting the manuscript or critically revising it for important intellectual content.
3. Final approval of the version to be published.
4. Agreement to be accountable for all aspects of the work and to ensure that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Individuals who meet all four criteria should be listed as authors.

Contributorship

Individuals who contributed to the work but do not meet the criteria for authorship should not be listed as authors. Such contributions may be acknowledged in the Acknowledgements section with their permission.

Examples include:

• Technical or laboratory assistance
• Data collection under supervision
• Administrative or logistical support
• Language editing or proofreading
