Statistical analysis was performed using two-factor ANOVA followed by the Bonferroni post-hoc analysis. One factor was "treatment" (SB or MV + LPS) and the other factor was "strain" (B6 or lpr). The analysis was designed to determine the overall effect of each of the factors, the presence of an interaction effect, and the comparison of "strain" for each level of "treatment". Data was generated using GraphPad Prism. A p value of less than 0.05 was considered significant.
