Self-reported sleep time across all days

ysleeptime_hr under Sleep Questionnaires/Sleep Habits in CCSHS variables

Calculated as a weighted average of self-reported sleep time from weekdays and from weekends (ysleeptime_hr = 5/7 *wd_slpdur_hr + 2/7*we_slpdur_hr)

Arousal Characteristics - Change in HR per hr of TRT
