Relationship Between Quartiles of GDF-15 and Anemia in Multivariable Cox Proportional Hazards Models

Covariates in Models^a	HR (95% CI)	p Value
Age, sex	1.17 (1.11, 1.23)	<.0001
Age, sex, log interleukin-6, serum iron, soluble transferrin receptor, ferritin, vitamin B₁₂ <200 pg/mL	1.17 (1.11, 1.24)	<.0001
Age, sex, log interleukin-6, serum iron, soluble transferrin receptor, ferritin, vitamin B₁₂ <200 pg/mL, congestive heart failure, diabetes mellitus, cancer	1.15 (1.09, 1.21)	<.0001

Note: ^aThese models compare the top quartile with the lower 3 quartiles.
