一个HRH和health outcome的RCT--perfect！

从Prof Grepin推荐的best 10中发现一个Pakistan做的聚簇RC Trial试验，看好研究真是过瘾。在给这篇文章的correspondence里，Davis引用UNICEF的数据"In the developing world, 440 of 100,000 births result in maternal death, as compared with 12 of 100,000 in the developed world."，可见这里面还有很多工作可以做。但是话说回来，本文的RCT结果显示的是纳入传统的接生员只对Prenatal mortality有作用，对maternal mortality没有显著效果。
