Table 7. Effect size of the change in LCI after reanalysis with different algorithms for signal processing and detection limits.
| Settings | Changed LCI | % change of standard LCI | # children with 5–10% change | # children with >10% change |
|---|---|---|---|---|
| Baseline | 8.55 ± 2.64 [6.29–14.94] | |||
| O2 drift correction off | 8.29 ± 2.18 [6.38–14.95] | -1.75 ± 7.95 | 5 (17%) | 5 (17%) |
| Dynamic CO2 correction off | 9.07 ± 2.60 [6.65–15.99] | 6.67 ± 5.23 | 15 (50%) | 5 (17%) |
| Integrated reinspired N2 off | 8.51 ± 2.57 [6.25–14.76] | -0.41 ± 1.65 | 0 | 0 |
| O2 response-time correction off | 9.24 ± 2.71 [6.63–18.05] | 8.65 ± 6.65 | 14 (47%) | 11 (37%) |
| Volume Sensitivity higher | 8.57 ± 2.63 [6.25–14.94] | 0.23 ± 0.64 | 0 | 0 |
The table shows mean ± SD [range] LCI after reanalysis of the tests with changed default algorithms for signal correction, mean ± SD change in percentage of standard LCI, number of children with a change between 5–10% and children with >10% change of standard LCI.
