Due to problems with EEG signals, arousals were ignored in scoring.

Overall quality of signal from EEG1 lead during sleep as assessed by scorer.

Overall quality of signal from EEG2 lead during sleep as assessed by scorer.

Study was scored sleep/wake rathen than with full sleep staging. This assessment is made by the scorer if there is not sufficient quality on EEG leads to do full R&K scoring. (0=no (full scoring); 1=yes (sleep/wake only))

Calculated - Summary metric of sleep disordered breathing events from the baseline screening visit.Estimated sleep duration, providing an approximation of total sleep duration (i.e. total sleep time) inferred from analysis of non-EEG channels Zhao et al., 2017 (PMID:27707441)There is a HeartBEAT specific respiratory event index measure :aphypi:. Details can be found in the Embletta scoring manual.

Estimated sleep duration, providing an approximation of total sleep duration (i.e. total sleep time) inferred from analysis of non-EEG channels Zhao et al., 2017 (PMID:27707441) Details about how the respiratory events were scored can be found in the Embletta scoring manual.
