Factors influencing further vertebral height loss following percutaneous vertebroplasty in osteoporotic vertebral compression fractures: A 1-year follow-up study

Table 3 Results of the binary multivariate regression analysis revealed significant associations with further height loss among osteoporotic vertebral compression fracture patients undergoing percutaneous vertebroplasty with cement augmentation
