  Baseline Characteristics

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
The required data for baseline results is participant-level data. This study is a comparison of lesion-level data sets, ie, a comparison of intra-participant data. It is not possible to segregate participant baseline data to one group or the other of the intra-participant datasets.
