Mean values for actigraphy (ACTI) outcome variables for the Sleep Intervention Program (SIP) and control groups at baseline, post-treatment and 4-month follow-up for sleep efficiency (panel A), number of nighttime awakenings (panel B), total nighttime wake time (panel C) and Total sleep time (panel D). Data presented here includes all available observations for actigraphy at each time point (N = 42 at baseline, N = 38 post-treatment and, N = 38 at 4-month follow-up; also see Supplementary Figures S27–S30 for evaluation of potentially influential data points).
