At screening, patient will have taken blood samples and performed hepatic vein pressure gradient.
After randomization, patient will be seen at follow up every 3 months to do blood sample and every 12 months to undergo hepatic vein pressure gradient , according to the guidelines.
In addition, metabolomics analysis will be performed at screening and every 3 months. The results will be analyzed in relation to emergence of decompensation during follow up period, in order to identify specific metabolomics characteristics that may be able to predict decompensation.
