Linear regression analyses for all data in 14 patients: (A) internal lung air volume change (AVC) versus external torso volume change (TVC) and (B) the spirometric tidal volume versus the TVC. The slopes (α = 0.950 and 1.053) are slightly off unity, largely due to patient #9 who has an unusually large maximum tidal volume in the fitting scale.
