Summary: The Informed Consent Action Network (ICAN) argues that sibling-control analyses in prenatal neurodevelopment research are often unstable and potentially biased, and therefore should not be used to dismiss potential risks from prenatal acetaminophen. They advocate for the FDA to weigh these studies alongside other evidence to justify a precautionary prenatal warning.
Please consider the attached comment and supporting references regarding the limitations of sibling-control analyses in prenatal neurodevelopment research. Recent methodological literature suggests that sibling comparisons may attenuate or obscure true associations in certain developmental exposure settings and therefore should not be treated as dispositive evidence against potential prenatal acetaminophen risk. These concerns are directly relevant to the ICAN citizen petition requesting precautionary prenatal warning language and informed consent.
