*Follow-up—baseline; p value for within-group change calculated using the paired-samples t test (urine volume) and the related-samples Wilcoxon signed-rank test (copeptin).
†The between-group difference in change from baseline to week 6 was compared using the independent t test (urine volume) and the Mann-Whitney U test (copeptin).
