Comparisons for means and standard deviation (±) between the children affected by obstructive sleep apnea syndrome (OSAS) and non-OSAS (nOSAS) children in nocturnal respiratory parameters.
| Nocturnal respiratory parameters | OSAS (n = 129) |
nOSAS (n = 264) |
t-test (df = 391) | p |
|---|---|---|---|---|
| Total sleep time (TST) | 6.84 ± 1.25 | 8.24 ± 0.96 | -12.252 | <0.001∗ |
| Apnea/hypopnea index (AHI)/hour | 13.84 ± 1.12 | 0.64 ± 0.12 | 189.53 | <0.001∗ |
| Oxygen desaturation index (ODI)/hour | 10.19 ± 2.86 | 0.31 ± 0.21 | 55.893 | <0.001∗ |
| Oxygen mean saturation percentage (%) | 91.63 ± 1.39 | 97.15 ± 2.01 | -28.075 | <0.001∗ |
| Oxygen desaturation level percentage (%) | 7.89 ± 1.11 | 0.15 ± 0.12 | 112.111 | <0.001∗ |
Nocturnal respiratory parameters: total sleep time (TST), apnea/hypopnea index (AHI)/hour, oxygen desaturation index (ODI)/hour, oxygen mean saturation percentage (%), and oxygen desaturation level percentage (%). ∗p values < 0.05 are statistically significant. df: degrees of freedom.
