The relative changes of collagen features in reversible and irreversible patient groups pre-SVR and post-SVR. (A) The features of reversible patient were slightly improved, i.e. shrank from the blue line (pre-SVR) to the yellow line (post-SVR), especially for ATC CAR, which shows statistical significance. (B) The irreversible group’s profile is noticeably different from that of the reversible group. The ATC CFT increased and the ATC TRI decreased post-SVR with statistical significance. The decrease of ATC TRI is potentially associated with the increase of ATC CFT since the larger area occupied by the collagen might lead to a simpler network of the cellular tissue. (C) The absolute differences of the reversible (green line) and irreversible (red line) groups’ profile pre-SVR and post-SVR. (D) The relative differences in percentage of the reversible (green line) and irreversible (red line) groups’ profile pre-SVR and post-SVR.
