Bold-italic values denote statistically significant differences at the p <0.05 level.
Lower-case letters are used to identify the group that makes the difference. The same letters (such as a-a) indicate that there is no difference, different letters (such as a-b) indicate that there is a difference.
*Mean ± standard deviation.
**Median (IQR).
ICU: intensive care unit; MACCE: major adverse cardiac and cerebrovascular events
