Enter a Baseline Interval

Overview

For most research projects, the first encounter is considered the baseline assessment. However, some projects include a run-in period or screening, thus the Baseline checkbox is used to indicate which interval is considered Baseline.  The baseline interval is used as a basis for calculating time from study onset.
