Table 3. HRs for all-cause mortality in the unmatched cohort for specified phosphate binder and adherence category.

Comparison Groups	HR (95% CI)	P
Adherent calcium vs. non-adherent calcium	0.88 (0.83-0.93)	< 0.001
Adherent sevelamer vs. non-adherent sevelamer	0.94 (0.89-0.99)	0.03
Adherent sevelamer vs. adherent calcium	1.02 (0.95-1.09)	0.6

Note: The HRs were obtained from models adjusted for age; sex; race; ethnicity; cause of end-stage renal disease; dialysis vintage; hematocrit value, vascular access type; baseline treatment with erythropoiesis-stimulating agents, vitamin D, β blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/renin inhibitors, calcium channel blockers, statin, and cinacalcet; baseline hospitalizations; and baseline comorbid conditions.
