a
In 3 months preceding the survey interview.
b
Results presented as weighted annual average.
c
Consists of model where the outcome variable was the number of controller medications taken and the predictor variable was WRA status, adjusted for age, sex, race/ethnicity, income, health insurance, current employment status, chronic obstructive pulmonary disease (COPD), and adverse asthma outcomes.
WRA, work-related asthma; PR, prevalence ratio; CI, confidence interval; Bold text indicates significance.
