METHODS A total of 9405 patients (79% men, mean age 68 years) participated in a cross-sectional study. HRQL was(More)

The aim of our study is to(More)
BACKGROUND Some patients with COPD may share characteristics of asthma; this is the so-called asthma-COPD overlap syndrome (ACOS). There are no universally accepted criteria for ACOS, and most treatments for asthma and COPD have not been adequately tested in this population. MATERIALS AND METHODS We performed a survey among pulmonology specialists in(More)
