*P values compares saline versus ropivacaine procedure.
†Non-parametric test (Wilcoxon-Mann-Whitney test) to compare median (IQR) and χ2 used to compare proportions.
DN4, evaluation of probability of neuropathic pain 0–10 (neuropathic > or =4); EQ-5D, standardized measure of health-related quality 5–25; NRS, Numeric Rate Scale; VAS, Visual Analog Scale.
