Heat shock protein 27 (HSP27) changes from preoperatively (Preop) to the end of surgery (T0), and 3 h (T3) and 20 h (T20) postoperatively displayed as median and 25th to 75th percentile in the three study groups. P values indicate the significance level at post hoc comparisons of mean ranks of pairs of groups when multiple comparisons of mean ranks for all groups, Kruskal-Wallis test showed significance.
