Noora is so effective that even if you measure their costs in the most conservative way, by dividing their entire budget by the number of lives saved, the cost of saving a life is the lowest I've seen. $1,235.
That is, indeed, way lower than anything I've seen. Has anyone looked into this?
I'm not an expert but skimmed the two documents that seemed most relevant. The mortality rate analysis of the study and how they derive the $1235 per life estimate from it.
Two things that I noticed, which jlewars didn't mention yet:
[Again not an expert, so don't make any conclusions based on what I write here.]
So, even if Noora Health's intervention was as effective as they suggest, the question of how well the intervention is scaled for mothers in other contexts is a separate question. (However, if they use additional funding in a similar context this is not such a big problem.)
