  1. Data are presented as mean (standard deviation).
  2. */**/*** Difference between good and poor sleeper significant at the 5%, 1%, and 0.1% level respectively (Hotelling’s T-square test on transformed value that maximizes multivariate normality).
  3. Good sleeper: global PSQI score < 5. Poor sleeper: global PSQI score ≥5.
