Notes: Cluster robust standard errors in parentheses; SNH = Safety net hospital; All regressions also include cancer specific hospital surgical volume measures and year dummies. Omitted insurance category is “private or military”; omitted age category, “<45”; omitted race category, “white”; omitted Charlson score, “0”; and omitted stage, “0–1.”
