| Variable | AUC (95% CI) | p value | Sensitivity, % | Specificity, % |
|---|---|---|---|---|
| Age | 0.78 (0.74–0.83) | 0.000* | 59 | 87 |
| FGF21 | 0.63 (0.57–0.69) | 0.000* | 91 | 32 |
| Calcium | 0.60 (0.54–0.66) | 0.001* | 92 | 22 |
| iPTH | 0.58 (0.51–0.63) | 0.012* | 60 | 54 |
| FGF21 + iPTH | 0.64 (0.58–0.69) | 0.000* | 60 | 60 |
| Age + calcium + iPTH + FGF21 | 0.84 (0.79–0.87) | 0.000* | 84 | 71 |
