Interestingly, among non-refractory TLE-HS patients (n = 15), the IL-10 levels showed a moderate negative correlation with the duration of epilepsy (r = − 0.585, p = 0.023, Fig. 3), and this correlation did not change after adjusting for age (r = − 0.536, p = 0.042), sex (r = − 0.556, p = 0.039), and both age and sex (r = − 0.549, p = 0.052). Here, IL10 is linked to epilepsy.
