One year mortality rates, stratified by neighborhood SES^*

	Highest SES	High SES	Medium SES	Low SES
Total, N	2,748	2,600	2,638	2,586
Deaths, n (%)	794 (28.9)	857 (33.0)	860 (32.6)	978 (37.8)
Days to death†, med (IQR)	365 (192–365)	365 (108–365)	365 (100–365)	365 (74–365)
HR (95% CI)	1.0 (ref)	1.17 (1.07–1.29)	1.17 (1.06–1.29)	1.38 (1.26–1.51)
Adjusted HR (95% CI)‡	1.0 (ref)	1.08 (0.98–1.19)	1.11 (1.01–1.22)	1.21 (1.10–1.33)

CI, confidence interval; HR, hazard ratio; med, median; IQR, interquartile range; SES, socio-economic status.

^*Neighborhood SES was estimated using ZIP code Social Deprivation Index (SDI) scores; scores were then split into quartiles.

^†Among those who died within 1-year of their ostomy placement.

^‡Adjusted for patient sex, age, race/ethnicity, Charlson Comorbidity Index (CCI) score, frailty score, and cirrhosis; age, CCI score, and frailty score were modeled as restricted quadratic splines; 30-day complications and ostomy revision were not included in the model because they were considered mediators.
