The AST-to-Platelet Ratio Index (APRI) is a simple and accessible marker, but its concordance with imaging-based parameters such as liver stiffness measurement (LSM), controlled attenuation parameter (CAP), and ultrasound-based fatty liver grading remains uncertain. This study assessed the relationship between APRI and both imaging-based and biochemical fibrosis measures, particularly the FIB-4 score, in diabetic individuals. Methods:
This cross-sectional study included 400 patients with type 2 diabetes mellitus who underwent liver fibrosis assessment. APRI and FIB-4 scores were calculated using routine laboratory parameters. FibroScan® was used to obtain LSM and CAP values, while fatty liver was graded by ultrasound. Associations between APRI and categorical fibrosis or steatosis grades were analyzed using Kruskal-Wallis and Wilcoxon-Mann-Whitney U tests, and statistical significance was tested with the Chi-square test (χ²). Correlations between APRI and continuous variables (LSM, CAP, and FIB-4) were evaluated using Spearman’s rank correlation coefficient (ρ), with thresholds defined as strong (ρ ≥ 0.70), moderate (ρ = 0.40–0.69), weak (ρ = 0.10–0.39), or none (ρ < 0.10). A p-value < 0.05 was considered statistically significant. Results: No significant association was found between APRI and imaging-based fibrosis (χ² = 0.764, p = 0.858) or ultrasound-based steatosis grades (χ² = 1.351, p = 0.717). APRI showed weak, non-significant correlations with both LSM (ρ = 0.02, p = 0.629) and CAP (ρ = 0.03, p = 0.525). In contrast, APRI demonstrated a strong and statistically significant correlation with the FIB-4 score (ρ = 0.88, p < 0.001). Patients with FIB-4 >2.67 had significantly higher APRI values compared to those with intermediate FIB-4 scores (1.07 vs. 0.52, p < 0.001). Discussion:
APRI strongly correlates with the FIB-4 score, however it shows no meaningful association with elastographic or sonographic indicators of liver fibrosis or steatosis in diabetic patients. These findings suggest that APRI may be reliable as a biochemical marker but has limited utility in reflecting imaging-based liver pathology.
Figure: Figure X. Scatter plot demonstrating a significant positive linear correlation between the AST to Platelet Ratio Index (APRI) and the FIB-4 Score. Each dot represents an individual data point, with the fitted regression line and 95% confidence interval shaded in blue. The strong association highlights the concordance between these two non-invasive markers of hepatic fibrosis.
Figure: Figure. Scatter plot showing the relationship between the AST to Platelet Ratio Index (APRI) and liver stiffness measurement (LSM, in kPa) obtained via transient elastography. The plot demonstrates a weak or absent linear correlation, as indicated by the near-horizontal regression line and wide confidence interval. This suggests limited concordance between APRI and LSM as markers of liver fibrosis in this cohort.
