  • Note:—Data are calculated P values. DRG indicates dorsal root ganglion.
  • * McNemar test. NA, the data is not applicable for the McNemar test because only 1, 2, and 0 pair DRGs are different in the position, respectively, at L1, L2, and L4 levels.
  • † Paired t test. Data in parentheses are t values.
