Globulin-platelet model predicts minimal fibrosis and cirrhosis in chronic hepatitis B virus infected patients

Table 2 Noninvasive simple fibrosis models composed of routine clinical and laboratory parameters

Fibrosis test	Calculation
FI	8.0-0.01 × PLT (× 109/L)-ALB (g/dL)
APRI	AST (IU/L) × 100/PLT (× 109/L)
FIB-4	Age (yr) × AST (IU/L)/PLT (× 109/L) × ALT (IU/L) 1/2
FCI	ALP (IU/L) × T.bil (g/dL)/ALB (g/dL)/ PLT (× 109/L)
Age-AST model	Age (yr)/AST (IU/L)
AP index	Age (yr)/PLT (× 109/L)

PLT: Platelet count ; ALB: Albumin; ALT: Alanine aminotransferase; ALP: Alkaline phosphatase; T.bil: Total bilirubin; AP index: Age-PLT ratio; AST: Aspartate aminotransferase; APRI: AST-platelet ratio; FI: Fibrosis index; FCI: Fibrosis-cirrhosis index.
