  • Include Subjects With No Encounters: This attribute determines if a subject should be included in the data set  
    • Check this box to include a subject that does not have any encounters from the list of intervals selected on the Intervals tab, the encounter data will be all null
    • Uncheck this box to only show subjects that have at least one encounter from the list of intervals selected on the Intervals tab
