Fig. 1From: Surgical intervention for vertebral metastases may benefit lung cancer patients no less than other patients: a retrospective studySurvival curves of patients with spinal metastases from lung (LK) versus prostate, breast, or thyroid primary tumor (PB) versus other cancers (OT). The postoperative survival period differed significantly among the three groups (P = 0.00). Pairwise comparisons using the log rank test revealed the survival period of the LK group to be significantly shorter than that of the PB group (P = 0.01), but there was no difference between the LK and OT groupsBack to article page
