No, this is the original claim:
> but it turns out that there are a decent amount of good studies showing a link between fluoride in water and (slightly) lower IQ when pregnant mothers ingest the fluoride.
Then the parent replied that this IQ link is lacking evidence, which it's not, per the meta-analysis I cited.
For fluoride measured in water, associations remained inverse when exposed groups were restricted to less than 4 mg/L or less than 2 mg/L but not when restricted to less than 1.5 mg/L
There were limited data and uncertainty in the dose-response association between fluoride exposure and children’s IQ when fluoride exposure was estimated by drinking water alone at concentrations less than 1.5 mg/L.
Which is not a claim that was being discussed in this subthread, since the original claim being refuted specify any such qualification.
