The changes from diagnostic PSG to pressure titration PSG between REM rebounders and non-REM rebounders. The figures showed the changes of diagnostic and pressure titration PSG in TST (A), SE (B), SL (C), WASO (D), Arousal Index (E), %N1 (F), %N2 (G), % N3 (H), % REM (I), AHI (J), Mean duration of apneas and hypopneas (K), Nadir SpO2 (L), Mean SpO2 (M), ODI (N) between REM rebounders and non-REM rebounders. a, comparison of diagnostic PSG parameters between REM rebounders and non-REM; b, comparison of pressure titration PSG parameters between REM rebounders and non–REM rebounders; c, comparison of the changes from pressure titration to diagnostic PSG parameters between REM rebounders and non-REM rebounders and * p < 0.05, **p < 0.01, ***p < 0.001. AHI apnea–hypopnea index, BMI body mass index, ODI oxygen desaturation index, PSG polysomnography, REM rapid eye movement sleep, SE sleep efficiency, SL sleep latency, SWS slow wave sleep, SpO2 pulse oxygen saturation, TST total sleep time, WASO wake after sleep onset, REM rapid eye movement sleep.
