These results should be useful to healthcare providers in assessing lung function declines observed in individuals.” A retrospective review of cross-sectional studies. Cause of death determined by death certificates. Data suggest serial FEV1 in coal miners with lung disease may aid in the management of the disease. If there is a loss of over 90ml/year then the risk of death increases.
