Coefficients of exercise allocation in ANCOVA models predicting subjective sleep outcomes

Outcome	Estimate for exercise allocation* (β)	Standard error (β)	95% Confidence interval		P
Exhaustion before sleep	0.15	0.15	−0.15	0.44	0.32
Mental balance before sleep	0.00	0.18	−0.35	0.36	0.99
Nocturnal psychosomatic symptoms	0.03	0.09	−0.15	0.21	0.73
Recuperation after sleep	0.31	0.17	−0.01	0.64	0.06
Sleep quality	0.20	0.19	−0.18	0.58	0.31

*Allocation was coded as follows: 1 = control, 2 = exercise.

All models used baseline values of the outcome as well as minimization factors (sex, age, PHQ9 score, and PSQI score) as covariates and allocation as the independent variable. The coefficient for allocation is the difference of the mean change score in the exercise group compared to the control group.
