HRs of baseline quartiles of FGF23 for all-cause mortality
| Quartile | FGF23 values | Crude HR (95% CI) | Model 1 HR (95% CI)a | Model 2 HR (95% CI)b |
|---|---|---|---|---|
| 1 | Lowest to 1829 | Ref | Ref | Ref |
| 2 | 1829–4383 | 1.20 (0.79–1.83) | 1.16 (0.76–1.76) | 1.08 (0.69–1.70) |
| 3 | 4384–12 209 | 0.94 (0.60–1.45) | 1.10 (0.71–1.71) | 1.12 (0.68–1.83) |
| 4 | 12 210 to highest | 0.72 (0.45–1.16) | 1.05 (0.65–1.70) | 1.08 (0.62–1.88) |
Cox regression, intention to treat analysis. Results are shown as HRs with 95% CIs. All models are adjusted for transplantation by adding transplantation as a time-varying covariate.
a
Model 1 = adjusted for age.
b
Model 2 = Model 1 plus adjustment for sex, diabetes, history of CVD, dialysis vintage, residual kidney function and phosphate.
