I am working on a project trying to answer the question of COVID mortality rate of the hospitalized among the racial groups. I selected race/ethnicity through the already built-in defaulted demographics race/ethnicity on the ‘feature analysis’ section of the cohort characterization in Atlas. As I tried to run this cohort characterization through Atlas, I noticed on the output that the total percentage of the racial groups does not equal 100%. So, this tells me that the built-in defaulted demographics race/ethnicity selected on the feature analysis did not include all possible values (eg. Null, unknown, others…etc). So I was wondering if there was a way I can edit or create a race/ethnicity for the feature analysis selection?
