Change of N₂MBW results after reanalysis with different environmental conditions.

Change of N2MBW test results of 30 children (10 with CF, 10 former preterm and 10 healthy children) after simulation with changed environmental conditions (temperature, pressure and BTPS correction). N2MBW results of the standard test were compared to the test with changed setting parameter by Wilcoxon signed-rank test. We compared lung clearance index (LCI), Scond raw (Scond) and Scond corrected for tidal volume (Scond*VT), Sacin raw (Sacin) and Sacin corrected for tidal volume (Sacin*VT). The arrows reflect the statistical significance (Wilcoxon Signed Rank Test): ↓↓ difference of p < 0.001, ↓ p < 0.01, (↓) p < 0.05, ↔ no significant change.
