Figure 4. Number of transitions of sleep-wake stages and self-reported sleep quality.

Figure 4

(A) Number of transitions from wakefulness to N1, N2, N3 and REM sleep (all P>0.05). (B) Number of transitions from N1 to wakefulness, N2, N3 and REM sleep (N1 to N3: P Moc*Mid′<0.05, P Mid*Mid′<0.05). (C) Number of transitions from N2 to wakefulness, N1, N3 and REM sleep (all P>0.05). (D) Number of transitions from N3 to wakefulness, N1, N2 and REM sleep (all P>0.05). (E) Number of transitions from REM sleep to wakefulness, N1, N2, and N3 (REM sleep to wakefulness: P Moc*Mid′<0.05, P Moc*Moe<0.05). (F) Self-reported score of sleep quality (P Moc*Mid<0.001, P Moc*Mid′<0.001, P Moe*Mid<0.01, P Moe*Mid′<0.001).
