Multivariable logistic regression analyses for poor QOL.

Time Points	Variable	aOR	95% CI	p
Year 1	Insomnia	5.889	1.840–18.845	0.003
Year 2	Fatigue	22.783	4.493–115.515	<0.001
	Anxiety	13.985	2.627–74.461	0.002
Year 3	Comorbidity	5.056	1.275–20.051	0.021
	Fatigue	9.070	2.167–37.954	0.003
	Depression	6.540	1.641–26.069	0.008

QOL = quality of life, aOR = adjusted odds ratio, CI = confidence interval. Variables entered into the Year 1 model were type of surgery, dyspnea, insomnia, and anxiety; variables entered into the Year 2 model were type of surgery, fatigue, pain, insomnia, anxiety, and depression; and variables entered into the Year 3 model were type of surgery, comorbidity, fatigue, nausea/vomiting, pain, dyspnea, insomnia, appetite loss, anxiety, and depression.
