h. Research Gap: A research gap is an area where no or little research has been conducted. It is a topic or area where the generation of new knowledge could be beneficial. Identifying research gaps can help shape the direction of future studies by highlighting areas that have been overlooked or under-researched.

i. Informed Consent: Informed consent is a process in which a participant is informed about all aspects of the trial, including potential risks and benefits, before deciding whether to participate. It is a fundamental ethical requirement for research involving human participants. The participant should be competent, the consent should be voluntary, and the participant should be informed about the potential risks and benefits.

j. Publishing and Co-authorship under the Vancouver Protocol: The Vancouver Protocol is a set of guidelines for authorship on scientific papers, established by the International Committee of Medical Journal Editors (ICMJE). According to the protocol, authorship credit should be based on substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data; drafting the article or revising it critically for important intellectual content; and final approval of the version to be published. All authors should meet these conditions. The protocol also provides guidelines for resolving disputes over authorship.
