Latency of thermal pain (LTP). Preoperative and postoperative LTP at each time point. b On day 28 after surgery, the LTP in each group was compared and analyzed. Asterisks indicate that the difference between the two groups was statistically significant. Three asterisks indicate p < 0.001, two asterisks indicate p < 0.01, and a single asterisk indicates p < 0.05. Number sign indicates that compared with the PBS group, p < 0.01, the difference was statistically significant
