Values are presented as median [interquartiles] or mean ± standard deviation. Body weight change: difference between pre- and after 24 hours of operation. Intraoperative fluid amount: P < 0.05 between each group. Intraoperative estimated blood loss and urine output: P < 0.05 between Group Low vs. Group Cutoff & High. Net fluid balance: P < 0.05 between Group Low vs. Group Cutoff & High. Bonferroni correction was done.
