Diagnostic Tool | Frequency (%) or Median (IQR) | Clinical staging |
|---|---|---|
AST to Platelet Ratio Index (N = 129) | ||
Median (IQR) | 0.36 (0.24–0.60) |  |
 < 0.5 | 87 (67.4) | Normal liver architecture |
0.5–2.0 | 30 (23.3) | Moderate to significant fibrosis |
 > 2.0 | 12 (7.6) | Cirrhosis |
Fibrosis-4 Score (N = 134) | ||
Median (IQR) | 0.80 (0.48–1.27) |  |
 < 1.45 | 106 (79.1) | Normal liver architecture |
1.45–3.25 | 19 (14.2) | Moderate to significant fibrosis |
 > 3.25 | 9 (6.2) | Cirrhosis |
Liver ultrasound imaging (N = 71) | ||
| Â | 49 (69.0) | Normal liver architecture |
