Model performance in the hold-out test set and configuration parameters.

	AUROC	ACC	Recall	Spec	F1	AP	No. Features (1, 2, 3 grams)
GOS	0.94 [0.93–0.95]	0.77 [0.75–0.80]	0.77 [0.75–0.80]	0.92 [0.92–0.93]	0.77 [0.75–0.80]	0.65 [0.62–0.69]	243 (166, 65, 12)
mRS	0.90 [0.89–0.91]	0.59 [0.567–0.62]	0.59 [0.57–0.62]	0.93 [0.93–0.94]	0.59 [0.57–0.62]	0.41 [0.38–0.44]	536 (397, 116, 23)

The bootstrapping results in 95% confidence intervals are in parenthesis. AUROC – Area under the receiver operating characteristic curve, ACC – accuracy, Spec – specificity, AP – average precision, GOS – Glasgow Outcome Scale, mRS – modified Rankin Scale, C – inverse of regularization strength. For both outcome models, the configuration parameters selected for C and warm start were 0.05 and “True”, respectively.
