Table 3 Cut-off values for FIB-4 and APRI in predicting significant fibrosis (F ≥3).
| AUC | Cut-off | SEN% | SPE% | P value | PPV% | NPV% | |
|---|---|---|---|---|---|---|---|
| FIB-4 | 0.70 | >1.06 | 70 | 75 | 0.001 | 76 | 87 |
| APRI | 0.68 | >0.38 | 65 | 86 | 0.001 | 66 | 87 |
| AUC – area under the curve; APRI – Aspartate Aminotransferase-to-Platelet Ratio Index; FIB-4 – Fibrosis-4 Index; NPV – negative predictive value; PPV – positive predictive value; SEN – sensitivity; SPE – specificity. | |||||||
