Table 5. ANN outputs distribution across each phase.

All model outputs mostly fall into the corresponding phase definition ranges (e.g., in Phase 1: BIS 0–40 row, the output largest part (59.3%) belongs to 0–40 range bin) except phase 3: BIS 65–85 row, during which the top one falls into 40–65 bin.

BIS level	Model output
	n	0–40	40–65	65–85	85–100
BIS 0–40	15,467	9171 (59.3%)	6,219 (40.2%)	76 (0.5%)	1 (0%)
BIS 40–65	13,952	4218 (30.2%)	9,466 (67.8%)	248 (1.7%)	20 (0.1%)
BIS 65–85	2,274	47 (2.1%)	958 (42.1%)	851 (37.4%)	418 (18.4%)
BIS 85–100	2,202	24 (1.1%)	547 (24.8%)	623 (28.3%)	1008 (45.8%)
