SD: Standard deviation; ICU: Intensive care unit; LOS: Length of stay; CPB: Cardiopulmonary bypass; DC: Direct current

^*Use of independent sample t-test for comparison of mean variables between the two groups

^**Use of chi-square test for comparison of variables’ frequency distribution between the groups

^***Use of Fisher’s exact test for comparison of variables’ frequency distribution between the groups
