The concentrations of the three DPs present in all patients, Gly-Asp (A), Gly-Pro (B) and Ala-Glu (C) and anserine (D), the DP with the highest concentration on average in CSF of patients without (w/o) and with epilepsy (in fmol/µl). Anserine was detectable in 12 patients without and with epilepsy, Gly-Asp, Gly-Pro and Ala-Glu in 20 patients without and in 23 patients with epilepsy. The mean values of these DPs tend to be higher for patients with epilepsy than for patients without epilepsy, but did only reach statistical significance in anserine. Mann–Whitney test was used for statistical evaluation. Displayed is mean ± SD. *p < 0.05. ns = not significant
