Fig. 4. Ablation analysis on the prediction of adverse glycemic events, evaluated on the 12 T1D subjects.

a MCC scores for hypoglycemia prediction. b MCC scores for hyperglycemia prediction. The lower bounds significantly improved hypoglycemia prediction, while the use of wristband data enhanced MCC scores for all the prediction horizons. The lower and upper hinges of boxplots show the Q1 and the Q3, respectively. The central lines indicate the median, while the whiskers extend to 1.5 IQR.
