| Parameters | R | P value | Parameters | R | P value |
|---|---|---|---|---|---|
| AI | 0.252 | <0.01* | N2, % of TST | −0.003 | 0.952 |
| ODI | 0.064 | 0.151 | N3 duration | −0.173 | <0.01* |
| ESS | 0.09 | 0.04* | N3, % of TST | −0.225 | <0.01* |
| Sleep efficiency | 0.036 | 0.42 | R duration | 0.023 | 0.612 |
| sleep latency | −0.105 | 0.02* | R, % of TST | 0.01 | 0.821 |
| R latency | −0.062 | 0.17 | AOS | −0.19 | <0.01* |
| N1 duration | 0.131 | <0.01* | LOS | −0.242 | <0.01* |
| N1, % of TST | 0.144 | <0.01* | MOD | 0.273 | <0.01* |
| N2 duration | 0.016 | 0.713 |
AI – arousal index; AOS – average oxygen saturation; ESS – Epworth Sleepiness Scale; LOS – lowest oxygen saturation; MOD – mean oxygen desaturation; ODI – oxygen desaturation index, TST – total sleep time. AHI adjusted and * means P<0.05.
