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))

1=Sleep staging problem - scoring stage1/stage2 unreliable (when K-complexes and sleep spindles do not have show their classical morphology and distinction between Stage 1 and Stage 2 is doubtful (characteristic for the studies with low voltage EEG))

1=Sleep staging problem - scoring wake/sleep unreliable (when the clarity of the EEG makes distinguishing the transition unreliable)
