Table 4 Characteristics of patients with positive delta pulse pressure (dPP > 0) and patients with negative delta pulse pressure (dPP < 0). Results were expressed as mean and standard deviation or as median and interquartile range for quantitative parameters depending on distribution, and as an absolute value and percentage for qualitative parameters. The p-value corresponds to the comparison between patients with positive delta pulse pressure (dPP > 0) and patients with negative delta pulse pressure (dPP < 0)
