From: The total-breath method yields higher values of DLCO and TLC than the conventional method
Association between the FEV1 Z-Score, and either the ratio (panel A) or the difference (panel B) between TLCCS determined by the conventional method and TLCTB determined by the total-breath method, divided by TLCbody from body plethysmography. The two methods are indicated by different symbols (see insert) and collectively indicated by TLCdiffu on the vertical axes. The horizontal line indicates the value of one (panel A) or zero (panel B)
