CDS, HGM-2, MODEL3, FI and FCI should be included in an algorithm for diagnosing F = 4.
The same indexes should be included in an algorithm for identifying advanced fibrosis.
For diagnosing F ≥ 2, FIB4, GUCI, APRI and HGM-2 are the best indexes.
A combination of indexes could be used for the diagnosis and follow-up of liver fibrosis stages.
HGM-2 and FIB4 show very good results for mono-infected CHC patients.
