Summary help text

Create one or more cohorts for the study. Once created, upload GUIDs identified for inclusion using a comma separated list. Note that a research subject may only be listed once in a cohort (e.g. included or excluded). When you upload your subjects, promoted GUIDs will be displayed to avoid any duplication of subjects. Prior to upload subjects, it is recommended that you first verify that you are using the most appropriate GUID for a subject using the Resolve Subject Identifiers utility.
