Figure 4. From: Flow-Volume Parameters in COPD Related to Extended Measurements of Lung Volume, Diffusion, and Resistance.

R5–R20 (a) and Fres (b) measured by impulse oscillometry in controls (healthy smokers) and COPD patients with GOLD stage 1–4. *significant difference compared to healthy smokers, significant difference compared to GOLD1, significant difference compared to GOLD2, #significant difference compared to GOLD3, one symbol flagging P < 0.05, two symbols flagging P < 0.01 and three symbols flagging P < 0.001. Data presented as individual dots together with median with interquartile range.

RV% (a) and TLC%p (b) measured by body plethysmography and single breath helium dilution with CO-diffusion. Difference in RV% (RV%pBP−SB) (c) and TLC% (TLC%pBP−SB) (d) measured by body plethysmography and single breath helium dilution with CO-diffusion in controls (healthy smokers) and COPD patients with GOLD stage 1–4. *Significant difference compared to healthy smokers, significant difference compared to GOLD1, significant difference compared to GOLD2, #significant difference compared to GOLD3; §significant difference between measurement from body plethysmography compared to single breath helium dilution with CO-diffusion, one symbol flagging P < 0.05, two symbols flagging P < 0.01, and three symbols flagging P < 0.001. Data are presented as median (IQR) in (a)-(b) and individual dots together with median with interquartile range (c)-(d).
