A: 90-day gap, no change of treatment episode when medication changes;

B: 60-day gap, no change of treatment episode when medication changes;

C: 180-day gap, new treatment episode when medication changes

All three scenarios refer to a 2-year follow-up window from the first medication event, with carry-over within the observation window, only for the same medication, considering dosage change.
