Abozid, Hazim; Patel, Jaymini; Burney, Peter; Hartl, Sylvia; Breyer-Kohansal, Robab; Mortimer, Kevin; Nafees, Asaad A.; Al Ghobain, MohammedBackground: Chronic cough is a common respiratory symptom with an impact on daily activities and quality of life. Global prevalence data are scarce and derive mainly from European and Asian countries and studies with outcomes other than chronic cough. In this study, we aimed to estimate the prevalence of chronic cough across a large number of study sites as well as to identify its main risk factors using a stan...
COPD: should diagnosis match physiology?
Studnicka, Michael; Horner, Andreas; Sator, Lea; Buist, A. Sonia; Lamprecht, Bernd; Zhong, NanShan; Liu, Shengming; Lu, Jiachun; Ran, Pixin; Wang, DaliWe are very grateful to Dr. Vanfleteren and colleagues for commenting on our data regarding overdiagnosed COPD2 and for putting this evidence into the framework of the current understanding of the disease.

Overdiagnosis of COPD in subjects with unobstructed spirometry
Sator, Lea; Horner, Andreas; Studnicka, Michael; Lamprecht, Bernd; Kaiser, Bernhard; McBurnie, Mary Ann; Buist, A. Sonia; Gnatiuc, LuisaBackground: There are several reports on the underdiagnosis of COPD, while little is known about COPD overdiagnosis and overtreatment. We describe the overdiagnosis and the prevalence of spirometrically defined false-positive COPD, as well as their relationship with overtreatment across 23 population samples in 20 countries participating in the BOLD Study between 2003 and 2012. Methods: A false-positive diagnos...
