Example of neural network prediction for the first 24 h of a 62 year old man with Hepatitis C cirrhosis presenting with 2 days of intermittent coffee ground emesis and lethargy. Initial Glasgow Blatchford Score = 14 (a) Continuous risk prediction of the neural network through the first 24 h with the threshold set above 0.5 for detecting need for transfusion. The arrows indicate need for transfusion during that time period. (b) Measurements of Heart Rate, Systolic Blood Pressure, and Hemoglobin occurring during the first 24 h.
