India is called to be a hub of clinical research, considering a huge patient pool across the country it becomes equivalently important to understand what an potential participant carries his/her perception on clinical trials. This book helps us in understanding the perception of Patients, Parents (Pediatric Trials) and Healthy Volunteers (Phase I Trials) in Indian Population. Considering diverse population multiple parameters (Strata) were taken into consideration (i.e. gender, economy, locations, education, etc.) to have a good/fair comparable data. Perspective of the selected population was studies keeping different parameters in focus such as ethics, confidentiality, trust, participation method, processes, regulations, influence of different parameter, etc. Studying all these parameters under one roof helped us in getting more crisp and reliable data.
