SEP group averages of the individual runs across two visits recorded from Cz-Fz during stimulation with 0.5 Hz at the BD (a, n = 20 subjects) respectively TG (b, n = 20 subjects) and 3.1 Hz at the pudendal nerve (c, n = 40 subjects). Run1, run2, run3, run4, and run5 are indicated in black, red, blue, green and orange, respectively (without baseline correction). T-curves of differences between baseline corrected individual runs 2–5 to run 1 (run2-run1: red dashed, run3-run1: blue dashed, run4-run1: green dashed, run5-run1: orange dashed) are shown for BD (d), TG (e) and pudendal nerve (f). T-values above 2.021 (for pudendus: 1.990) and below -2.021 (for pudendus: -1.990) were considered as significant. Significant differences between runs are highlighted in grey. Responder rate is displayed in % across the individual runs (open symbols) as well as the combined runs (filled symbols, consider that some symbols of the different frequencies overlay) of the runs for BD (g) and TG (h) and pudendal nerve (i) with 0.5 Hz indicated by black circles, 1.1 Hz, dark grey squares, 1.6 Hz, light grey up-pointing triangles, and 3.1 Hz, black down-pointing triangles, respectively.
