no flaming. Just a good discussion as it sounds like you are familiar with how it workI’m sure I will get flamed, but the current consensus at an academic level is that existing guidelines are overly generous, especially in children. The basic gist is that any blood lead level is harmful (but as I’ve said, we all die of something).
I would say that if you were trying to study the effects of ingesting game on BLLs, you would try to look for statistically significant increases in a population, not just whether those who consume game had levels requiring intervention.
So statistical significance is important, and measure P Value (maybe some folks read this and aren't familiar) is how we gauge it.
P value is generally not considered part of a small sample set study - which these are. P values of 0.05 would be min to achieve significance. A P value of .0005 would be very significant. The lower the number, the less variance in the data and more reliable it is
To achieve that kind of data, we need a control group, and randomization, and blinding of the data with at at least 60 people and more likely something around 200-300 to show any hope of a really good of P Value.
These studies weren’t powered to look at statistical significance, they merely looked at trackable levels. I included them only to answer the OP question of does it transmit and is it possible.
