Covariates in Models	HR (95% CI)^a	p Value
Age, sex	1.51 (1.32, 1.73)	<.0001
Age, sex, log IL-6, serum iron, sTfR, ferritin, vitamin B₁₂ <200 pg/mL	1.51 (1.31, 1.73)	<.0001
Age, sex, log IL-6, serum iron, sTfR, ferritin, vitamin B₁₂ <200 pg/mL, congestive heart failure, diabetes mellitus, cancer	1.41 (1.21, 1.64)	<.0001

Note: ^aHR = Hazard ratios expressed per 1 SD of GDF-15; CI = Confidence interval.
