Prior to randomization, median urine output and net fluid balance were numerically greater in the furosemide group compared with tolvaptan group but did not approach statistical significance due to large variability. There were no significant differences in median urine output or net fluid bal- ance between groups at 24 h or any time point up to 96 h, either cumulatively or for each 24-h interval. There were no significant differences in median systolic or diastolic blood pressure or heart rate between the groups at any time point. Self-rated dyspnoea score or proportion of subjects with at least moderate improvement was not different between groups at 24 or at 96 h or study drug termination (data not shown). Urine output and fluid balance comparisons are sum- marized in Figures 1 and 2. Vitals are summarized in Supporting Information, Table S1.
