ITT analysis ⁺ P-values between groups determined by two-tailed t-test, and Mann-Whitney U test. Overall p-values determined by analysis of variance and analysis of covariance (for comparison of repeated measures). In one patient from the UTR group only absolute fluid overload values could be measured; relative fluid overload values could not be calculated by the BCM device due to technical issues, resulting in deviation of the FO value from ECV
