TL;DR: Spirometric prediction equations for the 3–95-age range are now available that include appropriate age-dependent lower limits of normal for spirometric indices, which can be applied globally to different ethnic groups.
Journal ArticleDOI

TL;DR: Airway obstruction should be defined byFEV1/FVC and FEV1 being below the LLN using appropriate reference equations, and marked negative age dependency is demonstrated.
Journal ArticleDOI
Interpreting lung function data using 80% predicted and fixed thresholds misclassifies more than 20% of patients.
TL;DR: Using lung function tests on their own with 80% predicted and fixed cut points to determine whether a test is abnormal could misdiagnose > 20% of patients referred for pulmonary function tests.
