A biopsy in mid-2008 showed Metavir F1/F2 (two pathologists studied the specimen, one giving it an F1, the other an F2), which correlates with an
APRI between 0.5
and 1. A recent Fibroscan gave me F3/F4, which correlates with my most recent APRI of 1.38. So everything seems to hold together.
If you're interested in reading up on the APRI index, here are a couple of references:
