The GOLD 2011 document proposed a new classification system for COPD combining symptom assessment by COPD assessment test (CAT) or modified Medical Research Council (mMRC) dyspnea scores, and exacerbation risk. We postulated that classification of COPD would be different by the symptom scale; CAT vs...
All studies defined COPD severity based on the Global Initiative for Obstructive Lung Disease (GOLD) classification. Meta-analysis was conducted to analyze the vitamin D levels between mild–moderate (GOLD 1 and 2) COPD and severe–very severe (GOLD 3 and 4) COPD. Severe–very severe ...

This IPCRG Guideline on the management of COPD in primary care is fully consistent with GOLD guidelines. It highlights the goals of COPD treatment and the need for spirometric testing to make the diagnosis. It covers the classification of the disease according to disease severity, non-...
GOLD uses theforced expiratory volume (FEV1)test from your pulmonary function test to categorize the severity of COPD into stages. The forced expiratory volume (FEV1) shows the amount of air a person can forcefully exhale in one second.
Model 1 was adjusted for potential confounders and GOLD B-D, and model 2 was additionally adjusted for potential mediators (see Table 2 for details). Covariates were identified a priori and directed causal diagrams [24] guided classification into confounders and mediators. In sensitivity analysis ...

The mean number of AECOPD before enrollment was 1.6±1.9 episodes, and ~60% of patients belonged to GOLD group D according to the guideline classification. Table 1 Definition of overtreatment and undertreatment for different groups of COPD patients Overtreatment (presence of these medication ...
Severity classification of COPD has been defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) into four stages, mild (Stage I), moderate (Stage II), severe (Stage III) and very severe (Stage IV). Classification is determined by spirometric measurements using post-bronchodi...
