slp_eff5
Sleep Efficiency: the proportion of total sleep duration in in-bed period from type II polysomnography
|
Sleep Efficiency: the proportion of total sleep duration in in-bed period from type II polysomnography
Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep, while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time. Conventionally, this variable could be described as the ratio between total sleep time (TST) and time in bed (TIB). |

Sleep Maintenance Efficiency: the proportion of sleep duration in sleep period from type II polysomnography
|
Sleep Maintenance Efficiency: the proportion of sleep duration in sleep period from type II polysomnography
Sleep duration (i.e. total sleep time, TST) is the interval between sleep onset and sleep offset time while asleep. Sleep period is just the interval between sleep onset and sleep offset time. |
