Figure 4 Adjusted odds ratios (95% confidence intervals) for all-cause and COPD-related healthcare resource utilization and COPD exacerbations during the 12-month follow-up period per 30-day delay of triple therapy. Results from logistic regression models controlling for age, sex, payer type, index exacerbation type (moderate vs severe), urban residence, index year, baseline comorbidities and tobacco use, baseline exacerbations, baseline short- and long-acting maintenance therapy use, nebulizer use, oxygen therapy, and number of COPD-related primary care provider and pulmonologist visits.
