Maternal Fluoride Consumption During Pregnancy May Lower Children's Intelligence (npr.org) 4 points by freditup 6y ago ↗ HN
[–] gus_massa 6y ago ↗ From the research article:> A 1-mg/L increase in MUFSG was associated with a 4.49-point lower IQ score (95% CI, −8.38 to −0.60) in boys,> but there was no statistically significant association with IQ scores in girls (B = 2.40; 95% CI, −2.53 to 7.33).> A 1-mg higher daily intake of fluoride among pregnant women was associated with a 3.66 lower IQ score (95% CI, −7.16 to −0.14) in boys and girls.I'm not sure about the notation, but the results look pretty close to include the null hypothesis, where the change is 0.
