Performance Measures between Icobrain and Expert Reference Values for Acute Intracranial Lesions and Cistern Volumes and for Midline Shift

	Acute intracranial lesions	Cisterns
Volume difference (mL)	0.07 (−7.73, −7.47)	–0.01 (−1.66, −1.21)
Absolute volume difference (mL)	8.83 (2.02–17.05)	1.48 (0.70–2.26)
Classification accuracy	0.92	—
ICC	0.91	0.94
Dice	0.73 (0.55–0.81)	0.70* (0.66–0.73)
Precision	0.75 (0.63–0.87)	0.72* (0.67–0.79)
Sensitivity	0.75 (0.61–0.84)	0.69* (0.64–0.74)

	Midline shift
Shift difference (mm)	–0.22 (−0.88, −0.76)
Absolute shift difference (mm)	0.86 (0.37–1.48)
Classification accuracy	0.89
ICC	0.93

^*For cisterns, Dice, sensitivity, and precision are reported for volume >5 mL.

Except classification accuracy and ICC, all other measures are presented in median (25^th-75^th) percentiles.

ICC, intraclass correlation coefficient.
