Abbreviations: d.f., degrees of freedom; KW, Kruskal–Wallis test statistic; NS, not significant; P, approximate χ2P value; T0, basal measurement; T24, measurement at 24 hours. Groups: sham control (C), sham control MgSO4-treated (C-Mg), septic (S) and septic MgSO4-treated (S-Mg). Data are expressed as means ± standard deviation.
Dunn's multiple comparisons test: aseptic versus sham control, P < 0.05; bseptic versus sham control MgSO4-treated, P < 0.001; cseptic MgSO4-treated versus sham control MgSO4-treated, P < 0.01. Paired serum magnesium levels were compared within groups using a Wilcoxon signed rank test. Two-tailed P values are shown in the last column.
