Reconcilable Differences: Results

Published in Asthma

Reconcilable Differences: ResultsThe proportional odds assumption was tested for each model using a Score test. If the hypothesis of proportional odds was rejected (p 4 canisters, or 12 canisters) are reported for each association.

The distribution and univariate analyses of factors postulated a priori to be associated with SA P-agonist use are summarized in Table 1. The sample was comprised of 50% more women than men, and age was normally distributed across the entire range (median, 39.0 years; range, 19 to 50 years).
The sample was representative of all levels of asthma medication use and SES, and all participants reported having received at least some SA P-agonist in the previous year. Twenty-nine patients either did not know or preferred not to provide their annual household income and were therefore excluded from the analysis of income at the proximate level. Thirty-eight patients (23%) reported incomes > $70,000, 18 of which were > $100,000. One hundred twenty patients (59%) and 31 patients (15%) completed at least 1 year and 5 years of postsecondary education, respectively. The sample was also very contextually heterogeneous, with participants residing in neighborhoods with unemployment rates varying from 3 to 33%, and the prevalence of having received a bachelor’s degree ranging from 3 to 53%.
