↵* The multivariate stepwise model used the entire sample with entry criterion p=0.10. The results that fit this criterion for ACFs included diagnosis, needle approach and number of levels treated. Using MCF subjects only, the same procedure identified diagnosis and sex as the only two variables that fit the entry criterion.
ACFs, all compression fractures; MCFs, metastatic compression fractures.
