34 | 0.80 | 0.83 | 0.87 | 0.75 | |
62 | 0.98 | 0.41 | 0.71 | 0.95 | |
Nadir platelet (×109/L) | 17 | 0.59 | 0.96 | 0.95 | 0.62 |
33 | 0.91 | 0.76 | 0.85 | 0.85 | |
49 | 0.98 | 0.39 | 0.70 | 0.95 | |
Admission leukocyte (×109/L) | 17.3 | 0.52 | 0.83 | 0.81 | 0.54 |
Peak leukocyte (×109/L) | 18.7 | 0.64 | 0.74 | 0.78 | 0.59 |
PPV, positive predictive value; NPV, negative predictive value.
