I want to know the answer to the following question:
WHat strategy was found out to be more cost effective?
All the background I'm provided with is that "Development of a supplementation strategy should take into consideration the fact that vitamin A supplementation was less effective in reducing diarrhea incidence when compared to vitamin A and zinc supplementation, and that the latter strategy was estimated to be significantly more cost effective.". Is that enough to answer the question?
Answer: yes
