Diagnostic comparison of platelet parameters
| Cut-off point | AUC | Sensitivity | Specificity | PPV | NPV | LR+ | LR- | DA | |
|---|---|---|---|---|---|---|---|---|---|
| PLT | 272 (× 103 cells/μL) | 0.44 (CI: 0.33-0.55) | 48% | 65% | 57% | 57% | 1.39 | 0.79 | 57% |
| MPV | 7.75 fL | 0.41 (CI: 0.30-0.52) | 71% | 27% | 48% | 50% | 0.9 | 1.06 | 48% |
| PDW | 30.85% | 0.38 (CI: 0.27-0.48) | 69% | 49% | 56% | 62% | 1.36 | 0.63 | 58% |
PLT: platelet count, MPV: mean platelet volume, PDW: platelet distribution width, AUC: area under the receiver operating characteristic curve, PPV: positive predictive value, NPV: negative predictive value, LR+: positive likelihood ratio, LR–: negative likelihood ratio, DA: diagnostic accuracy.
