Clinical research refers to the study of health and disease in humans through controlled trials and studies. It aims to improve the prevention, diagnosis, and treatment of diseases by evaluating the effectiveness and safety of various interventions, such as medications, medical devices, procedures, and behavioral changes. Clinical research is essential for advancing medical knowledge, developing new treatments, and ensuring the safety and well-being of patients. Researchers in this field work with patients and volunteers to collect data, analyze results, and make evidence-based conclusions that guide medical practice.
