Diary: Minutes of Sleep on Night n3 before MSLT

min_n3 under Sleep Monitoring/Other Sleep Tests/Multiple Sleep Latency Test (MSLT) in WSC variables

avg_orp_n3 under Sleep Monitoring/Polysomnography/Electroencephalogram in SHHS variables

Average Odds Ratio Product (ORP) in all 30-s epochs during manually scored sleep stages. ORP is a continuous index of sleep depth and wake propensity. A value of 0 indicates very deep sleep, a value of 2.5 indicates full wakefulness. Search for all EEG variables within this dataset
