Manual revision of automated lung function grading results in an increase of accepted data and a relevant change in FEV1 and FVC

Background: In population studies, automated portable devices are used to measure lung function on location. A build-in automated quality algorithm selects technically correct lung function data for analysis. null Aim: To evaluate the performance of intergraded quality control in lung function testing equipment. null Methods: Lung function measurements in 6137 children (age 6 -13) were collected from the HITEA, FRESH and the PIAMA study.
