Table 3.

Multiple logistic regression models (unadjusted and adjusted) for dichotomous 55-Item frailty index and for worsening frailty index with three categories of cancer status: without cancer, remote cancer, and recent cancer

Analysis	Groups	Unadjusted OR (95 % CI)	p value	Adjusted OR (95 % CI)a	p value
FI > 0.25 in follow-up	Reference versus group 1	1 (0.61–1.64)	0.98	0.81 (0.39–1.64)	0.561
	Reference versus group 2	1.53 (1.04–2.26)	0.03	1.74 (1.15–2.61)	0.008
	Group 1 versus group 2	0.65 (0.35–1.21)	0.18	0.46 (0.2–1.04)	0.065
Worsening of the FI	Reference versus group 1	0.56 (0.39–0.8)	0.002	0.61 (0.38–0.99)	0.046
	Reference versus group 2	1.12 (0.81–1.54)	0.463	1.03 (0.74–1.43)	0.838
	Group 1 versus group 2	0.5 (0.31–0.8)	0.004	0.59 (0.95–2.96)	0.074

Reference corresponds to the group without cancer

Group 1 corresponds to the group with cancer of more than 10 years since diagnosis

Group 2 corresponds to the group with cancer of 10 years or less since diagnosis
