From: Retrospective evaluation of pain in patients with coccydynia who underwent impar ganglion block

|---|---|---|---|
Before the block | 7.4 ± 0,9 | 7.5 ± 1.1 | 0.729 |
After the block | 5.5 ± 1.5 | 4.5 ± 1.4 | 0.127 |
< 3 months | 5.2 ± 2.3 | 3.7 ± 1.2 | 0.085 |
3–6 months | 5 ± 2.5 | 3 ± 1.8 | 0.044 |
