Odds ratios for survival of 5-8 years and 8 years and more, relative to less than 5 years associated with FACT-O-TOI and change in FACT-O-TOI adjusted for patient covariates^a

Parameter	Estimate	SE	P b	ORa (95% CI)
Survive 5-8 y vs <5 y (ref)
FACT-O-TOI baseline	0.036	0.007	<.001	1.04 (1.02 to 1.05)
Change in FACT-O-TOIc	0.039	0.006	<.001	1.04 (1.03 to 1.05)
Survive ≥8 y vs <5 y (ref)
FACT-O-TOI baseline	0.046	0.007	<.001	1.05 (1.03 to 1.06)
Change in FACT-O-TOId	0.057	0.006	<.001	1.06 (1.05 to 1.07)

^aReference: survive less than 5 years: 827; survive 5-8 years: 227; survive 8 years and more: 233. Deleted for missing data: 415. CI = confidence interval; FACT-O-TOI = Functional Assessment of Cancer Therapy–Ovary Trial Outcome Index; OR = odds ratio; QOL = quality of life; ref = reference; SE = standard error.

^bData tested using 2-sided z-test.

^cOdds ratios adjusted for age, stage, grade, performance status, residual disease, and treatment.

^dChange measured from baseline to longest QOL follow-up of cycle 13, cycle 21, or post-treatment.
