Simple spirometry and body plethysmography have been routinely used in children aged> 5
years. New techniques based on physiologic concepts that were first described almost 50 …

The Global Lung Function Initiative (GLI) Network has become the largest resource for
reference values for routine lung function testing ever assembled. This article addresses …

The aim of the Task Force was to derive continuous prediction equations and their lower
limits of normal for spirometric indices, which are applicable globally. Over 160,000 data …

Background Maximal lung function in early adulthood is an important determinant of
mortality and COPD. We investigated whether distinct trajectories of lung function are …

Rationale: The long-term respiratory sequelae of infants born extremely preterm (EP) and
now graduating from neonatal intensive care remains uncertain. Objectives: To assess the …

Abstract Objectives-In 2000, the Centers for Disease Control and Prevention (CDC)
released a new set of childhood growth charts for the United States. These charts included a …

Background Reference values for lung function tests should be periodically updated
because of birth cohort effects and improved technology. This study updates the spirometric …

It is unknown what proportion of long-term lung function decline in cystic fibrosis (CF) is
explained by pulmonary exacerbations. The aim of this study was to determine how …

Reliable interpretation of pulmonary function results relies on the availability of appropriate
reference data to help distinguish between health and disease and to assess the severity …

Prediction bias in spirometry reference equations can arise from combining equations for
different age groups, rounding age or height to integers or using self-reported height. To …
