Does tylenol taken in pregnancy cause autism?
Correlation is not the same as causation. It's like how ice cream sales and drownings both spike in summer - but ice cream isn't drowning anyone. The real culprit? Hot weather drives both up.
Same here: pregnant moms taking more Tylenol might have infections or health issues that are the actual factors.
