paper "Efficacy and safety of tenofovir in preventing mother-to-infant transmission of hepatitis B virus:  
a meta-analysis based on 6 studies from China and 3 studies from other countries." The study is a  
metanalysis. It has been found 9 studies from the literatur. These 9 studies show heterogenity. The
