Quantitation of inflammation reactions at sensor implantation sites in normal and IL-1Ra transgenic mice. Average inflammation index values from weeks 1 to 4 by IL-1Ra genetic background. * represents the statistical significance (p < .05) of the difference between IL-1Ra~KO and IL-1Ra~OE inflammation index values for that week. † represents the statistical significance (p < .05) of the difference between IL-1Ra~KO and C57BL/6 control inflammation index values for that week. ‡ represents the statistical significance (p < .05) of the difference between IL-1Ra~OE and C57BL/6 control inflammation index values for that week. Error bars present standard errors of the inflammation index values for each individual week and genetic background. To test for statistical differences among all three genetic groups at once, Kruskal–Wallis tests were conducted on the inflammation index values as a nonparametric equivalent to analysis of variance for each week, with p values indicated at the bottom of the graph.
