 Abbreviations: d.f., degrees of freedom; KW, Kruskal–Wallis test statistic; P, approximate χ^{2} P value; SG, specific gravity. Groups: sham control (C), sham control MgSO_{4}treated (CMg), septic (S) and septic MgSO_{4}treated (SMg). Data are expressed as means ± standard deviation.
 Dunn's multiple comparisons test: ^{a}septic versus sham control, P < 0.001; ^{b}septic versus sham control MgSO_{4}treated, P < 0.01; ^{c}septic versus sham control, P < 0.01; ^{d}septic versus sham control MgSO_{4}treated, P < 0.001; ^{e}septic MgSO_{4}treated versus sham control MgSO_{4}treated, P < 0.05. A Mann–Whitney test was used for withingroup comparisons. Twotailed P values are shown in the last column.
