Perioperative cerebral hemodynamics measures for patients with biventricular congenital heart disease. Upper and lower borders of boxes represent the first and third quartiles, middle line represents the median, upper and lower whiskers represent the maximum and minimum values within 1.5 * IQR (IQR is the interquartile range, or distance between the first and third quartiles), and extra dots represent outliers. The statistical significance for comparisons is indicated with P values. *P values < .05. SaO2, Arterial saturation; SO2, cerebral oxygen saturation; OEF, cerebral oxygen extraction fraction; CBV, cerebral blood volume; CBFi, cerebral blood flow index; CMRO2i, cerebral oxygen metabolism index.
