Original article: "Prenatal paracetamol exposure and child neurodevelopment: a systematic review and meta-analysis" - https://www.thelancet.com/journals/lanogw/article/PIIS3050-5...
"Findings. 43 studies were included in the systematic review, and 17 studies in the meta-analysis. When considering sibling comparison studies, paracetamol exposure during pregnancy was not associated with the risk of autism spectrum disorder (OR 0·98, 95% CI 0·93–1·03; p=0·45), ADHD (0·95, 0·86–1·05; p=0·31), or intellectual disability (0·93, 0·69–1·24; p=0·63). There was also no association between paracetamol intake during pregnancy and autism spectrum disorder (OR 1·03, 95% CI 0·86–1·23; p=0·78), ADHD (0·97, 0·89–1·05; p=0·49), or intellectual disability (1·11, 0·92–1·34; p=0·28) when considering only studies at low risk of bias according to QUIPS. This absence of association persisted when considering all studies with adjusted estimates and those with more than 5 years of follow-up."
And why is it that someone claiming <x> causes autism such a common predictor of quackery?
I write "investigating" because trying to justify your crackpot theories that you've already decided are true isn't true scientific investigation.
Protects against acetaminophen!
