Evaluation of the attributable risk and diagnostic efficiency of these parameters for bone metastasis in 205 patients with stage IV primary lung cancer. a Multivariate logistic regression analysis to evaluate the attributable risk of these parameters for bone metastasis. OR values were presented by log2 transformation. OR: odds ratio, CI: confidence interval. * P < 0.05 was considered statistically significant. b ROC analysis to assess the diagnostic efficiency for bone metastasis of different combinations of the four independent diagnostic risk factors, including BME cytokines (OPG and PTHrP) and bone turnover markers (tP1NP and β-CTx)
