Table 1. Overview of exacerbation reporting in different parts of the world.

Publication	Country™	Number of participants (n)	Number or percentage of participants (n) reporting exacerbations across different studies
Chandra et al. 2009 [27]	North America	396	30% of patients reported the exacerbation immediately, while 70% of patients had a delay in reporting.
Hernandez et al. 2013 [32]	Canada	640	10% reported exacerbations.
Wilkinson et al. 2004 [26]	UK (East London)	128	1,099 exacerbations were recorded by the patients, of which 658 were reported to a physician (60%).
Trappenburg, 2011 [33]	Netherlands	141	17.3% contacted their primary physician after an exacerbation.
Xu et al. 2010 [24]	China	450	A total of 466 unreported (53%) and 410 reported exacerbations were recorded (47%).
Langsetmo et al. 2008 [25]	Canada	421	Less than one-third of exacerbations were reported.
