Figure 5. — A, Percent predicted lobar volume at TLC ([CT scan-measured lobar volume/predicted lobar volume at TLC] × 100) by GOLD stage for NHW subjects. B, Percent predicted lobar volume at TLC by GOLD stage for AA subjects. The pattern of hyperinflation appears to be relatively consistent between the races: the upper lobes exceed 100% of the predicted volume even in moderate airflow obstruction (GOLD II), whereas the lower lobes only exceed 100% of the predicted volume in very severe disease (GOLD IV). Data are presented as means and SDs. LLL = left lower lobe; LUL = left upper lobe; RML = right middle lobe. See Figure 1 legend for expansion of other abbreviations.
