However, we observed a strong correlation between SST and NK1R labelling index on single-stained sections (all cases P < 0.000, Supplementary Fig. 2B and C; SUDEP alone P = 0.001 Supplementary Fig. 2D; epilepsy controls P = 0.007; non-epilepsy controls P = 0.001). The gene discussed is SST; the disease is epilepsy.
