9. Plagiarism Detection

All manuscripts submitted to LNH&MC journals will be assessed through Turnitin plagiarism software to assess deceived and dishonest manuscript submission. Manuscripts containing similarity index higher than 20% will not be entertained and will be sent back to author for correction. Guidelines provided by ICMJE, PMC and HEC regarding plagiarism are being followed in LNH&MC journals which can be accessed at www.icmje.org , www.pmc.gov.pk/ and www.hec.gov.pk.

Plagiarism and Similarity Index

As per HEC and PM&DC Guidelines for Recognition of Publications and Journals 2018, “Plagiarism shall be a punishable offence and any author found guilty of plagiarism will be liable for disciplinary action”. It is ethically dishonest to submit plagiarized work. Authors are instructed to refrain from:

• Direct Plagiarism: When someone else’s work is transcribed word to word.
• Self-Plagiarism: Authors' previous self-work is presented without being permitted by other co-authors/professors.
• Mosaic Plagiarism: When the author’s language is slightly changed and phrases are used without using quotation marks.
• Accidental Plagiarism: When the author accidentally neglects to cite the source being quoted.

As per Turnitin plagiarism software, LNH&MC journals’ editorial board will make a decision if the author is found guilty of plagiarism.

10. Copyright/Undertaking

Authors who publish in LNHMC journals retain copyright to their work. Submission of a manuscript to the respective journals implies that all authors have read and agreed to the content of the undertaking form or the Terms and Conditions.

For potential studies, relating to human partners, authors are expected to seek the approval of (Regional / National / Institutional or Independent Ethics Committee or Review Board), obtain informed consent from adult research participants, and expression of approval for children aged over 7 years participating in the trial. Ensure the confidentiality of articles by mentioning participants' names, initials or hospital numbers, especially in illustrative equipment. When writing experiments on animals, specify that the institution’s or a national research council’s guide for, or a national law on the care and use of laboratory animals guide for the care and use of laboratory animals prepub was followed.

The name of the relevant institutional review board and approval number should be disclosed with ethical considerations in the article. The experimental procedure of animals should be as human as possible and the details of anesthetics and analgesics should be clearly stated. Ethical standards of experiments should be in line with the guidelines provided by the CPCSEA of Helsinki and the World Medical Association Declaration on the ethical principles of medical research for the study of experimental animals and humans, respectively.
