The literally bold-faced conclusion of your article is that no evidence exists that community water fluoridation affects childhood IQ.
We have a natural experiment running for 80 years where each arm of the experiment has N > 100e6. If there was going to be evidence of community water fluoridation lowering IQ, it would have emerged by now.
"The NTP monograph concluded, with moderate confidence, that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children".
They found drinking water with levels that lowered IQ. The actual conclusion was that higher levels (that were found in drinking water) lower IQ.
For lower levels the conclusion is we don't know how it effects IQ. The actual bold face conclusion is "More research is needed to better understand if there are health risks associated with low fluoride exposures".
The National Toxicology Program’s monograph failed peer review by the prestigious and independent National Academies of Science Engineering and Medicine. In fact, the document failed peer review twice:
in 2020: https://www.ncbi.nlm.nih.gov/books/NBK555056/
and again in 2021: https://nap.nationalacademies.org/read/26030/chapter/1
Why was this substandard draft even published?!
It seems that this team found what they wanted to find. Are they scientists or ideologues? Were they creating the 'evidence' for the San Francisco trail?
