Data is depicted as mean (SD) or median (IQR), if continuous. Categorical data is depicted as count (%). Of note, since the number of S100B measurements per patient varied, each individual does not contribute equal amount of data for the calculations of S100B. ECMO, extracorporeal membrane oxygenation; ICH, intracranial hemorrhage; VA, venoarterial; VV, venovenous.
