Correlations between ELV_I of upper lobes (A) and lower lobes (B) and DL_CO/V_A%P results.

Notes: DL_CO/V_A%P results were strongly correlated with ELV_I for the upper lobes (A), whereas this correlation was weaker for the lower lobes (B).

Abbreviations: DL_CO/V_A%P, ratio of the diffusion capacity for carbon monoxide to alveolar gas volume, measured as percent predicted; ELV_I, inspiratory emphysematous lobar volume; LLL, left lower lobe; LUL, left upper lobe; RLL, right lower lobe; RML, right middle lobe; RUL, right upper lobe.
