It may not be wrong, but the authors should provide a credible explanation of why their pre-war CDR is nearly half that of the UN Population Division. If the pre-war mortality rate was too low and/or if the population estimates were too high – because, for example, they ignored outflows of refugees from Iraq – the resulting estimates of the number of Iraqi “excess deaths” would be inflated.
因此两次《柳叶刀》研究所采用的战前总死亡率似乎太低了。这不一定有错，但作者应该提供令人信服的解释，说明为什么他们的战前总死亡率只有联合国人口司数据的一半。如果战前死亡率太低和/或估计人口数太高¾比如，举个例子，他们忽略了伊拉克难民的外逃¾那么由此得出的伊拉克“死亡增量”数据就会被夸大。
