Text: A 24-point BRAIN score was derived from INTERACT2 (C-statistic, 0. 73) based on baseline ICH volume (mL per score, 10 = 0, 10-20 = 5, > 20 = 7), recurrent ICH (yes = 4), anticoagulation with warfarin at symptom onset (yes = 6), intraventricular extension (yes = 2), and number of hours to baseline computed tomography from symptom onset (1 = 5, 1-2 = 4, 2-3 = 3, 3-4 = 2, 4-5 = 1, > 5 = 0) predicted the probability of ICH growth (ranging from 3. 4 % for 0 point to 85. 8 % for 24 points) with good discrimination (C-statistic, 0. 73) and calibration (Hosmer-Lemeshow P = 0. 82) in INTERACT1.
