Odds ratios and 95% confidence intervals for the relationship of prenatal acetaminophen exposure and (a) vocabulary size, (b) mean length of three longest utterances (M3L), and (c) complexity ≤25th percentile measured using the CDI at 26.5-28.5 months.^a The number of times acetaminophen was taken was not related to the odds of children having vocabulary scores ≤25th percentile. However, the number of times acetaminophen was taken during the third trimester was associated with slightly increased odds of male children having M3L and complexity scores ≤25th percentile.

^aModels were adjusted for maternal parity (nulliparous vs. ≥1), maternal education (<bachelor’s degree vs. ≥bachelor’s degree), and mean stress and depression scores during pregnancy.
