Continuous variables were presented as mean ± standard deviation (SD) or median (Q25, Q75). Categorical variables were shown as number (%). Student’s t-test or Mann–Whitney U test was used for continuous variables, and chi-square test was used for categorical variables. DHCA, deep hypothermic circulatory arrest. Bold values indicate p values less than 0.05.
