Declaration of Helsinki applies to _____.

The Declaration of Helsinki specifically outlines ethical principles for conducting medical research involving human subjects. Developed by the World Medical Association, it emphasizes the necessity of informed consent, the safety and well-being of participants, and the importance of scientifically sound and ethically justified research practices. This declaration serves as a cornerstone document, guiding researchers and institutions worldwide to ensure that human rights and ethical standards are upheld in clinical trials and biomedical research.

While maintaining patient confidentiality and addressing mental health disorders are undoubtedly important aspects of healthcare, they do not represent the primary focus of the Declaration of Helsinki. Additionally, policies regarding healthcare funding pertain more to economic aspects rather than ethical principles in research. Therefore, the correct understanding of the Declaration of Helsinki is that it directly pertains to the ethical guidelines for research involving human subjects.
