Why did you omit the sentence immediately after the one you quoted?
> The NTP review was designed to evaluate total fluoride exposure from all sources and was not designed to evaluate the health effects of fluoridated drinking water alone.
…or the following sentence, which they bolded to ensure the reader wouldn't miss it?
> It is important to note that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ.
So no, they very explicitly did not find that fluoride in drinking water concentrations was associated with lower IQ.
