difference between clinical trial and registry participation
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.
In all clinical trials, the typical process starts with a screening period. The screening period starts with the signing of the informed consent. During the screening period, inclusion/exclusion criteria for the study participation will be checked / tested. Subjects who meet all inclusion criteria and do not meet any exclusion criterion will be eligible to be randomized (in randomized trial) or to be dosed (in non-randomized trial).
