biostudies-literatureUnknown12(2)Shin E<h4>Background</h4>The effects of asthma, chronic obstructive pulmonary disease (COPD), or asthma-COPD overlap (ACO) on coronavirus disease 2019 (COVID-19) remain unclear.<h4>Objective</h4>We aimed to investigate the effects of chronic obstructive airway diseases such as asthma, COPD, and ACO on COVID-19.<h4>Methods</h4>In total, 5625 hospitalized patients with COVID-19 were divided into asthma, COPD, ACO, and control groups. A multivariate logistic regression analysis was performed to identify factors affecting the COVID-19 mortality rate. To find out whether chronic obstructive airway diseases such as asthma, COPD, and ACO affect COVID-19 mortality, 1:4 matching was performed, except for the ACO group alone due to a small number of patients.<h4>Results</h4>The mortality rates of asthma, Asia Pacific allergye21https://www.ebi.ac.uk/biostudies/studies/S-EPMC9066077biostudies-literatureImpact of asthma, chronic obstructive pulmonary disease (COPD), and asthma-COPD overlap on the prognosis of coronavirus disease 2019.PMC9066077Cho YSMoon HBLee JBShin ESong WJKwon HSAn JKim TBPark SYJin JYoo YSLee JHfalseImpact of asthma, chronic obstructive pulmonary disease (COPD), and asthma-COPD overlap on the prognosis of coronavirus disease 2019.<h4>Background</h4>The effects of asthma, chronic obstructive pulmonary disease (COPD), or asthma-COPD overlap (ACO) on coronavirus disease 2019 (COVID-19) remain unclear.<h4>Objective</h4>We aimed to investigate the effects of chronic obstructive airway diseases such as asthma, COPD, and ACO on COVID-19.<h4>Methods</h4>In total, 5625 hospitalized patients with COVID-19 were divided into asthma, COPD, ACO, and control groups.
