Abbreviations: d.f., degrees of freedom; KW, Kruskal–Wallis test statistic; P, approximate χ2 P value; SG, specific gravity. 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 < 0.001; bseptic versus sham control MgSO4-treated, P < 0.01; cseptic versus sham control, P < 0.01; dseptic versus sham control MgSO4-treated, P < 0.001; eseptic MgSO4-treated versus sham control MgSO4-treated, P < 0.05. A Mann–Whitney test was used for within-group comparisons. Two-tailed P values are shown in the last column. | ||||
