Risk Ratios using full model including age, sex, race, parent education and illness status. Model 1 compared those in with asthma and Non-asthma Chronic Illness separately to the healthy referent group. Model 2 compared the asthma and non-asthma chronic illness groups. (CI = Confidence Interval) Parameter estimates for controls reported for Model 1; models 2 and 3 estimates are similar.
