This document presents treatment threshold graphs from the National Institute for Health and Clinical Excellence (NICE) clinical guideline 98 on neonatal jaundice. The graphs show bilirubin thresholds for phototherapy and exchange transfusion in babies with hyperbilirubinemia. The guideline was developed by the National Collaborating Centre for Women's and Children's Health and thanks two researchers who allowed their Excel spreadsheet to be adapted in developing the treatment threshold graphs.
