What is the difference between "Program Follow-up interval before each cycle (in days)" and "MRL distribution prior to treatment, in days" under Program Settings?

Follow-ups are specific Interactions generated by the PMS based on the “Follow-up” configuration in Program > Information. They act as reminders in your Dashboard and need to be validated. The follow-up is sent at the selected interval (in days) before each treatment cycle. 

"MRL distribution prior to treatment" applies only to the MRL and define how long before treatment day you will be reminded to distribute the MRL. The reminder will show under the "Upcoming MedPacks (MRL, Donation or Voucher) to distribute" section of your Dashboard.
