slpprdp Total Sleep Duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type I polysomnography

Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).

Total time from lights out to lights on that is scored as sleep (rounded to nearest minute)
