Table 7:

MSL parameters describing the relationship between the log₂transformed sleep variables and MSL. The table is sorted with respect to p-value in a descending order. The parameter estimates are adjusted for age, BMI, sex, habitual sleep duration, minutes of sleep the two nights preceding the MSLT, and predicted WASO.
