Grouped Error Plot Graph of Bronchodilator Drug Response by Smoke x SES interaction group membership. Vertical lines denote the interquartile range (IQR) of group data; circles indicate the group median. Line color indicates dataset (full, male-only, female-only). Blue horizontal line indicates threshold for clinical response to bronchodilator treatment (ā FEV1āā„ā12%). ā FEV1 is the difference in % of Predicted FEV1 achieved before and after bronchodilator treatment. ā¼ means that the group medianā<āstudy population median; ā² means that the group medianāā„āstudy population median.
