NCT02300064

NCT00005382
To provide information necessary for the development of standards for peak expiratory flow (PEF) test performance in populations studies.
NCT00005370
To conduct a longitudinal study of the relationship between the rate of decline of pulmonary function and measurements of cortisol concentration and excretion in a sample of middle-aged and older men and their wives. The study tested the hypothesis that persons whose plasma cortisol concentrations were relatively low, albeit within the normal range, were predisposed to excessively rapid deterioration of pulmonary function during aging.
