  1. N = number of subjects with information of the questionnaire-derived variable outcome (i.e., not missing value). Adjusting for the following covariates: age, body mass index, season of the year in which the actigraphy recording was collected, number of recording days, number of free and workdays in the recording, per-subject total sleep time, per-subject sleep onset latency, per-subject wake after sleep onset, and per-subject number of awakenings.
  2. ρ, correlation coefficient; PSQI, Global Pittsburgh Sleep Quality Index Score; DBAS, Dysfunctional Beliefs and Attitudes Scale total score; TUQ, Technology Use Questionnaire total score; CGPA, cumulative grade point average; HADSD, Hospital Depression and Anxiety Scale Depression Score; HADSA, Hospital Depression and Anxiety Scale Anxiety Score; BP, blood pressure; FBG, fasting blood glucose.
  3. Statistically significant values (p-value < 0.05) are in bold.
