Objective: This is a meta-analysis comparing the efficacy of Tenofovir disoproxil fumarate (TDF) and Tenofovir alafenamide (TAF) in the treatment of chronic hepatitis B (CHB) so as to provide a reference for clinical medication.
Methods: Relevant literature about TDF and TAF in the treatment of CHB was searched in the literature databases, and two researchers two researchers conducted independent cross-screening conducted independent cross-screening according to the inclusion and exclusion criteria. The authors, publication time, research subjects. The literature quality was evaluated by, and outcome measures of the selected literature were extracted. The literature quality was evaluated using the Jadad scale and Cochrane risk-of-bias tool. Meta-analysis was conducted using the RevMan 5.3 software.
Results: After screening, 5 references were included, with a total of 5324 subjects. Patients who were treated with TDF and TAF were included in the TDF group and TAF group, respectively. The meta-analysis showed no significant difference in viral suppression between groups after 12 months of treatment (P > .05). Still, the alanine transaminase (ALT) normalization rate was higher, and the incidence of adverse reactions was lower in TAF group versus TDF group at 12 months after treatment (P < .05).
Conclusions: Both TAF and TDF are effective in the treatment of CHB, but the former is preferred due to its higher safety profile.
