  • ICH indicates intracranial hemorrhage.

  • a P from χ2 analysis.

  • b ICDMAP-90 was used to calculate ICD-9/AIS scores for the head region. ICD-9/AIS scores were categorized as mild (1–2), moderate (3), or severe (4–6).

  • c Other injuries included contusions (nonhead), burns, lacerations, and internal organ injuries. Retinal hemorrhages and fractures were categorized separately from other injuries and were not included as predictors of skeletal survey performance, because they may have been discovered during an evaluation for suspected abuse (such as ophthalmology examination or skeletal survey, respectively).
