Note.P1 indicates the P value of the VAS score or ODI at 4 weeks after treatment compared with the VAS score or ODI before treatment; P2 indicates the P value of the VAS score or ODI at 8 weeks after treatment compared with the VAS score or ODI before treatment; P3 indicates the P value of the VAS score or ODI at 8 weeks after treatment compared with the VAS score or ODI before treatment; P4 indicates the P value of VAS score or ODI comparison between two groups at different time points. ^∗indicates a significant difference (P < 0.05).
