BACKGROUND Prognosis in chronic obstructive pulmonary disease (COPD) is poorly predicted by indices of air flow obstruction, because other factors that reflect the systemic nature of the disease also influence prognosis. OBJECTIVE To test the hypothesis that a reduction in quadriceps maximal voluntary contraction force (QMVC) is a useful predictor of mortality in patients with COPD. METHODS A mortality questionnaire was sent to the primary care physician of 184 patients with COPD who had… CONTINUE READING
