Fig 4. Comparison of vertebra and pelvis metastases between pulmonary and prostate cancers.
The result shows that with an increase of bone metastases, the proportion of both of the vertebra and pelvis metastases of prostate cancer presents a gradually decreased tendency (χ2 = 57.2, p = 0.000), but that of pulmonary cancer does not present a significant difference (χ2 = 0.8, p = 0.657).
