Variable cutoff | Sensitivity (95%CI) | Specificity (95%CI) | PPV (95%CI) | NPV (95%CI) | AUC (95%CI) | P-value |
|---|---|---|---|---|---|---|
Ferritin > 548.5 ng/ml | 91% (75.6–98.1) | 74% (66.9–80) | 43% (19.7–51.5) | 97% (84.8–99.1) | 0.87 (0.79–0.94) | < 0.001 |
MPV > 9.5 fL | 96% (84.2–99) | 63% (29.2–44.3) | 25% (16.3–35.8) | 98% (85.3–99.5) | 0.83 (0.75–0.9) | < 0.001 |
