What was measured

Sleep efficiency measured by actigraph - Sleep efficiency is defined as the average percentage of time in bed actually spent sleeping

Analysis population: Data available only for participants who completed instrument for respective study visits.

Groups in this outcome

Circadian Active Bright White Light (BWL)

PEI Experimental Light: Ambient Light Fixture delivery of circadian active bright white light (BWL) installed in the patient's hospital room will turn on automatically and illuminate the hospital room from 7 to 10 AM each morning.

Circadian Inactive Dim White Light (DWL)

Comparison Light: Ambient Light Fixture delivery of circadian inactive dim white light (DWL) installed in the patient's hospital room will turn on automatically and illuminate the hospital room from 7 to 10 AM each morning.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
