Significant liver‐related events (SLRE) and liver‐related deaths were recorded during follow‐up (started the day of biopsy).</p> </sec> <sec id="apt12813-sec-0004" sec-type="section"> <title>Results</title> <p>During the median follow‐up of 9.5 years (3508 person‐years), 47 patients had a SLRE and 23 patients died from liver‐related causes. For the prediction of first SLRE, most blood tests allowed higher prognostication than Metavir F [Harrell C‐index: 0.811 (95% CI: 0.751–0.868)] with a significant increase for FIB4: 0.879 [0.832–0.919] (<italic>P</italic> = 0.002), FibroMeter: 0.870 [0.812–0.922] (<italic>P</italic> = 0.005) and APRI: 0.861 [0.813–0.902] (<italic>P</italic> = 0.039). Multivariate analysis identified FibroMeter, CirrhoMeter and sustained viral response as independent predictors of first SLRE. CirrhoMeter was the only independent predictor of liver‐related death. The combination of FibroMeter and CirrhoMeter classifications into a new FM/CM classification improved the liver‐prognosis assessment compared to Metavir F staging or single tests by identifying five subgroups of patients with significantly different prognoses.</p> </sec> <sec id="apt12813-sec-0005" sec-type="section"> <title>Conclusions</title> <p>Some blood fibrosis tests are more accurate than liver biopsy for determining liver prognosis in CHC. A new combination of two complementary blood tests, one targeted for fibrosis and the other for cirrhosis, optimises assessment of liver‐prognosis.</p> </sec> </abstract>
