A comparative analysis of the treatment response was conducted between patients with epidural spread (ES group) and those without epidural spread (NES group) at the first visit after PVB. The treatment response was determined by setting the minimum clinically important difference (MCID) as a reduction of more than 1 point on the pain numerical rating scale (NRS). In addition, the treatment responses were compared according to prevertebral spread, intercostal spread, and segmented medial spread (base, foraminal, and subarticular-central spread).
