Contribution to the misclassification of an individual clinical component interpreted within the GOLD 2011 classification matrix.

<p>The percentage indicates relative frequency of misclassified cases attributable to a given clinical component. A sole effect is responsible for misclassified cases due to an obvious error in interpretation of one specific primary clinical parameter. The combined effect is responsible for misclassified cases due to an obvious error in interpreting both clinical criteria on the same axis (mMRC dyspnea scale and CAT respective bronchial obstruction and number of COPD exacerbations/year). <i>Statistical probabilities were calculated of pair-wise contrasts as follows; mMRC dyspnea scale vs. CAT (p>0.05), mMRC dyspnea scale vs. bronchial obstruction based on post bronchodilator FEV1 (p<0.0001), mMRC dyspnea scale vs. number of exacerbations/year (p<0.0001), CAT vs. bronchial obstruction (p<0.0001), CAT vs. number of exacerbations/year (p<0.0001), bronchial obstruction vs. number of exacerbations/year (p<0.0001).</i></p
