Background Risk of exacerbations in individuals with mild chronic obstructive pulmonary
disease (COPD) in the general population is less well described than in more advanced …

Background Differences in previous exacerbation history may influence prognosis of chronic
obstructive pulmonary disease (COPD). We hypothesized that prognosis differs between …

Few studies have researched the independent effect of COPD severity on the risk of future
exacerbations adjusted by previous exacerbation frequency. We aimed to analyse the …

Background Whether risk of exacerbations of chronic obstructive pulmonary disease
(COPD) is influenced by severity of symptoms and maintenance treatment is unclear …

Background Recent studies evaluating the predictive value of different variables on future
exacerbations suggest exacerbation history as the strongest predictor. We examined the …

Introduction: COPD exacerbations may result in accelerated lung function decline and
increased mortality. Risk of exacerbations by baseline history was examined in COPD …

Introduction Exacerbations of chronic obstructive pulmonary disease are characterised by
increased symptoms such as dyspnoea, cough and sputum production and/or purulence …

Background Patients with chronic obstructive pulmonary disease (COPD) can be
categorized as having frequent (FE) or infrequent (IE) exacerbations depending on whether …

Introduction Early identification of preventable risk factors of COPD progression is important.
Whether exacerbations have a negative impact on disease progression is largely unknown …

Background The risk of exacerbation in chronic obstructive pulmonary disease (COPD)
depends on the severity of disease and other less well known factors. Predictive models of …
