Question and Methods: The study assessed the risk of brain injuries and fractures among infants <3 months with/without PECARN low-risk criteria by secondary analysis of PECARN data.
Findings: Of the 1081 infants included, 514 met the PECARN low-risk criteria and the sensitivity for clinically important traumatic brain injury (ciTBI), TBI and skull fracture were 96%, 92%, and 95% respectively.
Limitations: Lack of prospective validation in this specific age group.

Interpretation: Amongst infants <3 months old, PECARN low risk criteria are not as sensitive at predicting ciTBI, TBI and skull fracture
