Highest value in first 24 h (all other values are taken from admission blood draw).
Variables are listed from highest area under curve to lowest.
Bold values indicate area under curve >0.7.
CT, computed tomography; GCS, Glasgow Coma Scale; INR, international normalized ratio; ISS, Injury Severity Score; NLR, neutrophil to lymphocyte ratio; PICU, Pediatric Intensive Care Unit; PTT, partial thromboplastin time.
