Figure 3 Propensity score distribution plot comparing LABDs±ICSs users vs nonusers before and after matching.
Notes: Propensity score matching adjusting for age, gender, race, region, Medicaid eligibility, comorbidity score, number of hospital beds, medical school affiliation, type of hospital, type of admission, hospitalization 1 year before index hospitalization, ICU/CCU during index hospitalization, MV during index hospitalization, oxygen therapy 1 year before index hospitalization, pulmonary specialist visit 1 year before index hospitalization, length of index hospitalization stay and pulmonary specialist visit during index hospitalization.
Abbreviations: LABDs, long-acting bronchodilators; ICSs, inhaled corticosteroids; ICU, intensive care unit; CCU, coronary care unit; MV, mechanical ventilation.
