All values were taken at time of study enrollment unless otherwise noted. Continuous variables presented as median (quartile 1, quartile 3). PRA: prerenal azotemia, HRS: hepatorenal syndrome, and ATN: acute tubular necrosis. One participant received red blood cell transfusion instead of albumin. for PRA, for HRS, for ATN, and for other. for PRA, for HRS, for ATN, and for other.
