Effect of peripheral nerve blocks on pain scores
| Intervention | No of patients | NPS before treatment (median, IQR) | NPS after treatment (median, IQR) | P value |
| 1st PNB | 42 | 8.0 (6.0–9.0) | 1 (0.0–3.0) | <0.001* |
| 2nd PNB | 15 | 5.5 (4.0–7.3) | 2 (0.0–3.0) | 0.02* |
*Wilcoxon signed-rank test and Hodges-Lehmann median difference.
