Change of N₂MBW test results of 30 children after simulation with changed default algorithms for signal correction. Results of standard N₂MBW test were compared to the test with changed setting parameter by Wilcoxon signed-rank test and marked as follows: ↓↓ difference of p < 0.001, ↓ p < 0.01, (↓)p < 0.05, ↔ no significant change, ↔↔ no change at all.
