People unfamiliar with science will say "well we have one paper not showing a link and another paper showing a link." This is misleading because the papers are NOT created equally. The scientific/methodological rigor of Ahlqvist is much stronger.

However a paper by Prada et al (2025) claims to show an association between acetaminophen in pregnancy and autism. However this was a systematic review with a bunch of observational studies and limited control for confounding. There's so much heterogeneity. This is weak.

Currently, the strongest study we have that examined this is by Ahlqvist et al (2024), a study of 2.5 MILLION children...its a prospectively controlled study and adjusted for confounders (environment, genetic). It showed no association between acetaminophen in pregnancy & autism
