A @-point BRAIN score was derived from INTERACT@ ( C-statistic , @ ) based on baseline ICH volume ( mL per score , @ = @ , @-@ = @ , > @ = @ ) , recurrent ICH ( yes = @ ) , anticoagulation with warfarin at symptom onset ( yes = @ ) , intraventricular extension ( yes = @ ) , and number of hours to baseline computed tomography from symptom onset ( @ = @ , @-@ = @ , @-@ = @ , @-@ = @ , @-@ = @ , > @ = @ ) predicted the probability of ICH growth ( ranging from @ % for @ point to @ % for @ points ) with good discrimination ( C-statistic , @ ) and calibration ( Hosmer-Lemeshow P = @ ) in INTERACT@ .
