Reacción a "Reactions to study associating paracetamol use in pregnancy with attention and sleep problems in children"

It is in line with similar recent studies that may indicate that there is a causal relationship. Although longitudinal studies already assume some causality in the relationship, studies such as clinical trials are required to assume causality and effect.
