Mutually exclusive groups of bronchitics and non-bronchitics in males

Khosla, T.
RESUMO
Seven mutually exclusive groups of non-bronchitics and chronic bronchitics are derived from 10,816 steel workers questioned and examined at Port Talbot. These groups are based on various combinations of responses to the Medical Research Council questionnaire on cough, phlegm, dyspnoea, increased cough and phlegm, and chest illness. The groups are formed on defined criteria of (1) a reasonable number of men in each group; (2) impairment of lung function (FEV1) related to the severity of chronic bronchitis symptoms; and (3) impairment of lung function from certain other diseases.
