From: The efficacy of ultrasound-guided multifidus cervicis plane block versus greater occipital nerve block for cervicogenic headache

  GONB group MCPB group P value
Baseline frequency (no./week) 6.7 (5.2) 5.5 (4.3) 0.216
2-week visit frequency (no./week) 2.12 (2.30) 2.15 (2.16) 0.843
4-week visit frequency (no./week) 2.36 (2.40) 2.04 (2.09) 0.193
  1. GONB Greater occipital nerve block, MCP Multifidus cervicis plane block
  2. P ≤ 0.05 is significant
