Note:

a

adjusted for time, BMI, education level, household income, menopausal status, chemotherapy cycle length, and use of sleeping medications, antacids and insulin.

b

adjusted for time, age, marital status, and use of antacids, antidepressants and antihypertensives. SF-36 = Medical Outcomes Study Short Form. PCS = Physical Component Scale of SF-36, higher score indicates better HR-QOL. MCS = Mental Component Scale of SF-36, higher score indicates better HR-QOL. PSQI = Pittsburgh Sleep Quality Index, higher score indicates poorer sleep quality. TST = Nighttime total sleep time; TWT = Nighttime total wake time; NAPTIME = Daytime total nap time.
