Average sleep maintenance efficiency sleep in main sleep over all days from actigraphy

sawa24 under Sleep Monitoring/Actigraphy in HCHS variables

This variable is similar to the calculated variable sawa62; however, sawa24 is generated automatically by Actiware before data optimization.

Sleep maintenance efficiency is the ratio between sleep duration (i.e. total sleep time, tst) and sleep period in main sleep. Sleep duration is the interval between sleep onset time and sleep offset time while asleep, while sleep period is the interval between sleep onset time and sleep offset time.
