  1. N = 236 observations (n = 118 treatment participants, 2 observations per participant). Panel data estimations are random effects generalized least squared (GLS) regressions, with robust standard errors in parentheses. Partial eta-squared effect sizes in square brackets (rounded to three decimals) are from comparable ordinary least squares models, which yield coefficient estimates all similar in size and significance to the reported GLS estimates above. Cohort Fixed Effects included. Similar results are found when using alternative continuous sleep level controls in place of the binary SR indicator, as well as to using an IPW correction for sample selection (see Appendix Tables A8-A10). Nighttime (columns (5) and (6) above) is defined as the circadian evening that starts 2 h prior to habitual bedtime and lasts for 10 h.
