The following diagram represents visits as numbered "flags" with visit numbers. Each flag has 2 supports, one at the beginning of the visit and the other at the end of the visit. Note that visits 2 and 3 span epoch transitions. In other words, the transition event that marks the beginning of the run-in epoch (confirmation of eligibility) occurs during visit 2, and the transition event that marks the beginning of the study product administration epoch (the first study product administration of the study tobacco product) occurs during visit 3.
