Figure 4

Bland-Altman plot [24] of supine functional residual capacity measured by rebreathing of sulphur hexafluoride (FRCSF6) and by computed tomography (FRCCT) in 20 healthy subjects. The individual differences of paired measurements (y axis) did not depend on the magnitude of their average values (x axis). The mean difference (solid line; dotted lines represent the mean ± 2SD) was small.
