FST, furosemide stress test; N/A, not applicable; RRT, renal replacement therapy
aEarly RRT = RRT initiation within 6 h after randomization; standard RRT = RRT initiation according to standard indications
bOne patient died before RRT initiation. Two patients received RRT but later than 12 h due to the necessity for intervention
