The compare or merge feature

Below the tracker is the Compare or merge function:

The Compare or merge function allows you to compare the cohort you are currently defining with any other cohort available in your My Cohorts area.

A dynamic output shows you the number of patients who are in both cohorts, and the number in one cohort but not the other. If you are especially interested in one of these groups of patients, you can save it as a special type of cohort called a subgroup.
