ABR threshold in RA mice.

<p>Panel [A] compares the ABR threshold in RA mice when arthritis was asymptomatic (dashed line with filled circles, n = 16, 32 ears) and after footpads had become swollen (solid line with open triangles, n = 13, 3 died, 26 ears). Panel [B] compares the hearing thresholds in mice of different RA severity. The dashed line with filled triangles shows the SPL of the group with footpad swelled by <50% (n = 9, 18 ears). The solid line-open triangles show the group that had footpads swollen by >50% (n = 4, 8 ears). In both panels, the solid lines with open circles indicate the threshold of the normal controls (n = 4, 8 ears). The plots and statistics included both ears.
