# Matches the number in Figure 1. NPPG and NOCG indicate the neuropathic pain patient group and the nociceptive control subject group, respectively. Three × 2 χ² tests were conducted to compare the neuropathic pain patients and control subjects among the genotypes in each SNP. * Statistically significant differences between the neuropathic pain patients and control subjects. The p values in the table are the crude values without the Bonferroni correction.
