Fig. 2

Changes in vasopressor dependency index. Each box plot indicates medians, 25th and 75th percentiles, and whisker caps indicate 5th and 95th percentiles. White box plots indicate the low CVP group, and the diagonal-lined box indicates the high CVP group. An asterisk indicates a significant difference with p < 0.01, and a dagger indicates a significant difference with p < 0.05. There was a significant difference between the two groups in the repeated measure ANOVA. The vasopressor dependency index also significantly improved at 24 h in the low CVP group (0.28 to 0.16 mmHg⁻¹; p < 0.01) but not in the high CVP group (0.43 to 0.34 mmHg⁻¹; p = 0.10). Additionally, there was a significant difference in the index at 24 h between the two groups (p < 0.05)
