   * To compare how our model validates to these estimates: divide total mortality counts that occur in the SAM substates in our model by person time spent in the SAM superstate in our model among the uncovered population (at the national level)

+  * To evaluate how our model validates to this finding, we can compare the ratio of complicated SAM prevalence to total SAM prevalence in a scenario without treatment for uncomplicated SAM to a scenario with treatment for uncomplicated SAM. We would expect the difference to be >3 times as our modeled coverage differences are larger than what is expected in this publication.
