Worthwhile, yes, but harder to do. Those countries have less reliable data to work with, and not such a nice sharp cutoff. Here, babies born in the winters of 43-44 and 45-46 can serve as control groups for those born in the winter of 44-45.
The reliability of demographic data across Sub-Sahara Africa is a significant problem for a multitude of research disciplines.
But there's been a host of severe famines since World War II across the Sahel. It is possible that the reliability of birth data would have improved over this period to a degree sufficient to support research techniques.
In fact, there's been research along these lines in SSA already, especially regarding the impact of malnourishment on intellectual development among other factors.
Still, important research that goes to show that famines have generational effects that extend all the way to the genetic level.
I wonder what if there really is a significant difference between streaming a song in a store vis-a-vis placing it in a TV ad.
That said, of the two playlist selection companies that I have only just read about, the charge for streaming in-store is between $34 to $199 per location per month.
...p. 4 esp: 1) Analysis of ME/CFS Cases vs. Healthy Controls (case versus control means comparisons): We employed pseudo-likelihood ratio testing (8)2 to compare pMFI means between a) each disease severity group versus control and b) the equally-weighted average across all three severity groups versus control.
Is this in any way based on Amazon Polly?
