  1. Values represent sleep onset difference (minutes); Bolded values represent a significant change in the outcome variable from the previous strain level (p < 0.005). Standard errors are in parentheses. Statistical test used was generalized additive mixed models and contrast of estimated marginal means. Multivariate t-distribution adjustment method was used to adjust for multiple comparisons. Two-sided tests were used.
