Hazard ratios (HR) of cancer survival according to marital status, presence or absence of confidants and satisfaction level with confidants ^†

Characteristics	Marital status			Confidants			Satisfaction level with confidants
	Married	Unmarried	P‐value	Presence	Absence	P‐value	Extremely fairly satisfied	Somewhat satisfied– extremely dissatisfied	P‐value

Person‐months of follow up	70 (0–91)	73 (6–91)		71 (0–91)	65 (6–86)		71 (0–91)	67 (6–88)
No. deaths from all causes	50	7		46	11		43	14
Unadjusted HR	1.0 (referent)	0.6 (0.3–1.4)	0.26	1.0 (referent)	1.4 (0.7–2.7)	0.34	1.0 (referent)	1.0 (0.6–1.9)	0.96

Multivariable‐ adjusted HR	1.0 (referent)	0.8 (0.3–1.8)	0.53	1.0 (referent)	1.0 (0.5–2.2)	0.90	1.0 (referent)	0.7 (0.4–1.3)	0.21

^† Cox proportional hazards regression was used to adjust multivariable HR for age in years at cancer diagnosis (≤59, 60–69, ≥70), sex, smoking status (never‐smoker, ex‐smoker or current smoker), smoking status after surgery (never‐smoker, ex‐smoker, quit smoker or continued smoker), occasion of diagnosis (mass screening or health checkup, subjective symptoms, follow up for other diseases or unknown), pathological stage (IA, IB, IIA, IIB, or IIIA), and albumin.
