Comparison of the efficacy and safety of TAF, TDF, and LdT to prevent the transmission of hepatitis B in pregnant women: A retrospective study.

However, for all three groups of pregnant women who delivered babies with abnormal prenatal ultrasound screening, an expanded sample size may be needed for further observation.
