Figure S1 Relationship between different measurements of DLV% in 21 patients by two pulmonologists (A) and Bland-Altman plot (B). Correlation for measurements of DLV% between the two pulmonologists is significant (r = 0.980, P < 0.001). The Bland-Altman plot shows bias of 0.32% and 95% limits of agreement of −1.09 to 1.75%. Solid line, mean difference (bias) between the two measurements. Upper and lower dashed lines represent 95% limits of agreement.

Figure S2 Relationship between 21 paired measures of DLV% and Ldi (A and C, respectively) and Bland-Altman plot for each (B and D, respectively). Correlation for DLV% and Ldi is significant (r = 0.947, P < 0.001 and r = 0.929, P < 0.001, respectively). Bland-Altman plot shows bias for DLV% and Ldi of 0.34% and 0.01 cm, respectively, and 95% limits of agreements of −1.95 to 2.63% and −1.28 to 1.29 cm, respectively. Solid line, mean difference (bias) between the two measurements. Upper and lower dashed lines, 95% limits of agreement.
