Abstract
Positive and significant correlation coefficients were obtained by comparing the peak flow rate with MEFR, FEV1.0, and MBC in a selected United States urban population. Predictability of these latter three pulmonary function tests from the peak flow rate by the use of regression lines has been demonstrated but it should be emphasized that prediction errors may be large despite the high correlation values. A significant difference exists between the peak flow rates obtained by normal subjects compared with those of abnormal subjects, indicating the possible usefulness of the peak flowmeter in population studies of pulmonary disease.Keywords
