a Bland-Altman plot of TST estimated by Arc as compared to Actiwatch. b Bland-Altman plot of WASO estimated by Arc as compared to Actiwatch. Data shown represent comparison of Arc using a constant factor of 1.1 in the wake threshold formula comparing to results generated by the auto algorithm from the Actiwatch. c Bland-Altman plot of TST estimated by Arc as compared to Actiwatch. d Bland-Altman plot of WASO estimated by Arc as compared to Actiwatch. Data shown represent comparison of Arc using a wake threshold of 5 comparing to results generated by the low algorithm from the Actiwatch
