Sleep Efficiency: the ratio of sleep duration (i.e. total sleep time) to in-bed period from type I polysomnography
Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep (i.e. total sleep time, TST), while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time (i.e. time in bed, TIB). |

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