Association (linear regression) between preoperative sleep and satisfaction with hysterectomy.

	Satisfied with Procedure, β (SE)	Helpful in Alleviating Symptoms, β (SE)	Helpful in Treating Pain, β (SE)	Overall Treatment Satisfaction, β (SE)
Sleep diary (self-reported)
Naps (minutes)	0.82 (0.24)**	0.71 (0.35)*	0.71 (0.33)*	0.1 (9.2)
Actigraphy (objective)
Sleep-onset latency	0.08 (0.78)	0.13 (0.75)	0.19 (0.52)	0.53 (2.47)**
Sleep efficiency	0.05 (0.80)	0.1 (0.76)	0.14 (0.54)	0.39 (6.2)*

*P < .05, **P < .01. β = regression coefficient (represents the slope of the linear relation of the predictor variable and the outcome variable).
