What was measured

Sleep time measured by actigraph. Sleep time - average number of minutes the participant was asleep each night during the 5 day period. Baseline assessments were taken before transplant and day 2 is two days after transplant which is at least one week after the baseline.

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.
