WebAug 23, 2024 · Based on the lower observed lung function among non-White groups (Fig 1A), reference equations yield predicted values that are lower for non-White groups. Thus, for two people with the same absolute measure of lung function, the non-White individual will have a higher relative value (% predicted) compared with the White individual.
