The most representative variables for Clusters 1 through 5 were PSQI, IS, acceleration index, sleep time, and mesor, respectively.
In a past study on the effects of OnabotA on jaw motor events during sleep in sleep bruxism patients, no significant change from baseline was noted in usual sleep variables such as sleep efficiency, arousal index, sleep stages, or awakenings per hour during follow-up recordings [69].
Participation in the other three themes was not significantly predicted by the indicators of the lifestyle-related health, (body mass index, sleep disturbances, or depressive mood).
Five of the variables (the movement and fragmentation index, sleep efficiency, relative amplitude, intra-daily variability, intra-daily stability) were considered the outcome measures as decided a priori.
Internal consistency reliability of the sleep problems index, "sleep disturbance" and "sleep somnolence" showed good to excellent results whether the populations of the 6 countries were pooled or analyzed separately.
Sleep variables (sleep period time, sleep efficiency index, sleep onset latency, rapid eye movement (REM) latency, arousal index and percentage of sleep in REM, stage one, two and three) were scored manually by two scorers independently who were unaware of the experimental conditions, according to standardized criteria [ 20, 21].
The risk of developing headache is greater in individuals with a family history, smoking, high body mass index, sleeping problems, substance abuse, oversleeping, premenstrual period, stressful life events, hot/cold weather, menstruation, hanger and others [1, 18 20].
Practice of sleep hygiene and knowledge of sleep hygiene practices can be assessed with measures such as the Sleep Hygiene Index, Sleep Hygiene Awareness and Practice Scale, or the Sleep Hygiene Self-Test.
The EEG power in the delta frequency range (1 4 Hz; i.e., EEG delta power) during NREMS is widely used to index sleep need and we therefore followed the dynamics of this variable throughout the 2-day experiment.
*Multilevel logistic regression analysis adjusted for age, sex, ethnicity, procedure group, discharge year, insurance status, anesthesia type, peripheral block, transfusion, comorbidity index, sleep apnea.
