Class: Epoch

The planned period of subjects' participation in the trial is divided into sequential epochs. Each epoch is a period of time that serves a purpose in the trial as a whole. Epochs cannot overlap. The sequence of the epoch in the study is provided by the SequenceNumber attribute, the first epoch in the study being assigned the sequence number 1. Sequence numbers are subsequent.
