Serum levels of bone turnover markers and their abilities to diagnose bone metastasis in stage IV lung cancer patients. a, b Box plot distribution of the serum levels of the bone turnover markers tPINP and β-CTx from three groups, including the bone metastasis group (n = 127), the non-bone metastasis group (n = 78), and the healthy control group (n = 106). For details of the box plots, see the legend of Fig. 1. c ROC analysis of the ability of the serum bone turnover markers tP1NP and β-CTx to diagnose bone metastasis. d ROC analysis of the diagnostic efficiency of the combination of tP1NP and β-CTx
