A 2000 study found that two-thirds of parents bringing children under 7 to city emergency rooms did not know the difference between concentrated infants' acetaminophen drops and other acetaminophen formulations.

Notes on verification

Study existence, authors, journal, and year confirmed via multiple sources; exact 'two-thirds' statistic not independently verified from primary abstract text, but no contradicting evidence found and topic alignment is strong. [tier=silver indep_score=0.925 clusters=2 claim_tier=notable]
