Figure 4

Intraoperative and postoperative lactate levels. Mean (standard deviation) lactate levels are shown. Mean lactate AUC₁₅ values were 26 mmol/L × hour in the dexamethasone group and 20 mmol/L × hour in the placebo group (P <0.001). To convert lactate to mg/dL, multiply by 9.01. *Difference between groups statistically significant (P <0.001 after Bonferroni correction). AUC₁₅, area under the curve in the first 15 hours of postoperative intensive care unit stay; CPB, cardiopulmonary bypass; ICU, intensive care unit.
