Results of the multinomial logistic regression model (Lung Function=Adherence+CVs+e) that tests the association between adherence and lung function. No such association is found. Hypothesis 3: “Adherence mediates the relationship between SES and respiratory outcomes” cannot be supported.

N=110; RRR, Relative risk ratio; SE, Standard error; CI, Confidence interval.

^*P<0.05; Likelihood ratio chi² (24)=134.14***.

¹Reference category is low adherence (≤35).
