Table 2 Mean VAS pain scores in the non-collapse and collapse groupsᅟ

From: Risk factors of adjacent vertebral collapse after percutaneous vertebroplasty for osteoporotic vertebral fracture in postmenopausal women

  Non-collapse group (n = 47) Collapse group (n = 14) P-value between the 2 groups
Initial 9.7 ± 0.5 9.6 ± 0.8 P = 0.600
After 1 day 1.5 ± 0.7* 1.8 ± 1.0* P = 0.356
After 1 month 2.5 ± 1.0* 6.8 ± 1.2* P < 0.001
Final follow-up 2.6 ± 1.2* 3.3 ± 0.8* P = 0.015
  1. Parameters were compared between the 2 groups using the Student’s t-test
  2. *Significant difference. Compared with pre-operative VAS scores
