Survival of the severe fibrosis group was significantly lower than the two other groups (P<0.001).
Overall survival of the severe fibrosis group, treated or not, was significantly lower than that of paired controls (p<0.05).
Overall survival of the 1074 HBV patients, was significantly lower than that of paired controls (p<0.05).
P = 0.03 vs treated.
P = 0.047 vs treated.
Survivals of the treated patients were similar to those of the non –treated in different groups of viral load (p>0.05).
Overall survival of the group with high viral load was lower than that of paired controls (p<0.05).
Overall survival of the group with elevated ALT was lower than that of paired controls (p<0.05).
We used the manufacturers' definitions of normal FT (< = 0.27), normal AT (< = 0.29) and 3 classes for viral load in IU/ml.
