  1. Notes: The continuous measurement data were expressed by mean ± standard deviation (x ± s).
  2. VAS scores, visual analogue scale scores. JOA scores, Japanese Orthopaedic Association scores. F-SNRB, fluoroscopy-guided lumbar selective nerve root block. U-SNRB, ultrasound-guided lumbar selective nerve root block.
  3. *P < 0.05: compared with those before block, the scores of patients at each time point were significantly different.
