Sociology is the study of social behaviour or society, including its origins, development, organisation, networks, and institutions. It is a social science that uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order, disorder, and change.
Clinical trials registries collect basic health information from people who agree to be contacted about participating in future clinical trials or studies. A clinical trial is the study of new ways to prevent, detect or treat diseases or conditions.
This is in opposition to interventional studies in which subjects with a specific disease or condition are treated per an approved protocol and data are collected about the treatment. We say that registry studies are 'data driven' as opposed to interventional studies, which are 'protocol driven'.
