From the article: 

But antenatal care isn’t the norm for millions of women across Africa. In Tanzania, for example, the numbers are low. Even though over 90% of pregnant women attend at least once, only 51% make four or more visits during their entire pregnancy, according to the Tanzania Demographic and Health Survey. Only 24% of women make their first antenatal care attendance before the fourth month of pregnancy.
