Internal validation performance (using training data) for algorithm predictions up to 3 hours in advance.

Performance metric	Value
AUROCa	0.90
AUPRCb	0.62
Accuracy (95% CI)c	0.86 (0.80, 0.91)
Sensitivity	0.80

^aAUROC: area under the receiver operating characteristic curve.

^bAUPRC: area under the precision-recall curve.

^cOperating points for the algorithm were chosen to keep sensitivity at approximately 0.80.
