Figures

Fig 4
Fig 4. Displayed are the overall protein measurements in four different ways.
a) Comparing the ECoScreen and RTube EBC protein concentration after tidal breathing (TB) and hyperventilation (H) no statistical significant difference could be shown. Comparing the two manoeuvres, hyperventilation yielded higher concentrations than tidal breathing, but this difference was significant only in the ECoScreen (p < 0.05). b) When the overall protein concentrations were normalized to the volume of ventilated air, tidal breathing yielded higher normalized concentrations than hyperventilation (p < 0.05). c) The device had no influence on the total protein amount. Within the same device, hyperventilation yielded higher absolute amounts than tidal breathing (RTube: p < 0.05; ECoScreen: p < 0.005). d) By normalizing the absolute protein amount in EBC to the volume of ventilated air we did not find a significant difference between tidal breathing and hyperventilation.
Fig 5
Fig 5. AAT measurements are displayed in four different ways.
Regardless of the way the results were reported, the values for AAT derived through hyperventilation were consistently higher than the values derived through tidal breathing: a) concentration (p < 0.005); b) normalized concentration (p = 0.08) c) total amount (p < 0.005); d) normalized amount (p < 0.05).
