Correlation between CpG − 628 methylation level, determined via bisulfite and nanopore sequencing, and pressure pain threshold. Sanger bisulfite sequencing results and pressure pain thresholds were published previously [13, 14], nanopore sequencing was conducted in the present study. Bisulfite sequencing: R2 = 0.049, p = 0.426; nanopore sequencing: R2 = 0.048, p = 0.435
