From the article:
As noted in a recent report by our Commission, a one-year increase in schooling for girls is associated with reduction in mortality of 4.2% for children under the age of five.

And a case study from Brazil shows us low-income girls who participated in community preschool programs were two times more likely to reach fifth grade and three times more likely to reach eighth grade than their peers who did not attend preschool.

At the national level, there is significant variation among countries.
