Core Tip

Core tip: Recently, the American Association for the Study of Liver Disease suggested no preference between tenofovir (TDF) and entecavir (ETV) regarding potential long-term risks of renal complications. Over the years, renal safety has become a critical concern in nucleos(t)ide analog-treated patients due to the long-term use of these drugs. However, the existing studies do not show significant differences between the two drugs in renal dysfunction. We believe that our study could resolve the existing debate. This is the first meta-analysis comparing the influence of the two drugs on renal function using continuous variables. TDF statistically significantly decreases renal function compared to ETV, but the difference is inappreciable.
