Web4 jul. 2012 · According to the present recommendations, the relationship between FEV1 and FVC is quantified by means of the ratio of these indices, i.e. FEV1/FVC, introduced by Tiffaneau and Pinnelli about 60 years ago. If the value of FEV1/FVC is smaller than its lower limit of normal (LLN), a bronchial obstruction should be diagnosed. WebThere was a moderate, negative correlation between the two variables (r=−0.368, P<0.05), with lower FEV1 associated with older age.
