Fig 1. EOLC levels are lower in CSF from ictal migraineurs.

EOLC levels in CSF from clinical groups were measured by ELISA using specific anti-ouabain antibodies, described in Materials and Methods. ANOVA revealed that the three groups differed significantly; ictal were lower than interictal levels (paired Wilcoxon signed rank test), and lower than controls (Mann-Whitney). * p = < 0.05; *** p = < 0.001.
