Set cohort enrollment limit
In IWRS, you can set up the enrollment limits for each cohort of your period. Thus, the system automatically stops the subject enrollment process as soon as the limit is reached so that you do not have to track and control this process yourself. This helps you plan for a certain number of subjects to be allocated to different cohorts and receive certain dosages of medication to ensure the most efficient result of your investigation.
