Hazard ratio (95% CI) of the composite outcome of death or allograft loss according to 1 SD increase in natural log-transformed FGF23

	Phosphate Tertile 1 (<2.9 mg/dl)	Phosphate Tertile 2 (2.0 to 3.5 mg/dl)	Phosphate Tertile 3 (>3.5 mg/dl)
Crude	1.95 (1.34, 2.78)	1.85 (1.45, 2.35)	1.76 (1.57, 1.98)
	P < 0.001	P < 0.001	P < 0.001
eGFR-adjusted	1.78 (1.21, 2.59)	1.69 (1.30, 2.20)	1.40 (1.19, 1.65)
	P = 0.003	P < 0.001	P < 0.001
Fully-adjusted	1.67 (1.13, 2.47)	1.52 (1.12, 2.06)	1.37 (1.14, 1.66)
	P = 0.009	P = 0.008	P = 0.001

Full model is adjusted for eGFR, age, gender, systolic BP, body mass index, albumin, calcium, Charlson score, and the duration after transplant at the time of enrollment.
