CXCL10 and epilepsy: Although IP-10 levels were greater in nonepileptic cases overall, and specifically in the entorhinal cortex, when considering the epilepsy effect and epilepsy × brain region interaction (both p < 0.001 Tukey’s HSD), these effects may have been due to a few extreme nonoutlier values in the cortical specimens (see Additional file 2: Figure S2B).
