PSG Quality Assessment: Sleep Wake Scoring
Study scored sleep/wake rather than with full sleep staging if there is not sufficient quality on EEG lead. Studies scored as sleep wake have all sleep stages scored using a default of Stage 2 and no arousals are scored.(0=no (full scoring); 1=yes (sleep/wake only)) |
