Table 3 C index and time-dependent area under the receiver operating characteristic curve

			Time-dependent AUROC
	C index	(95% CI)	2 months	4 months	6 months	12 months	24 months
Bone metastases	0.689	(0.662–0.715)	0.738	0.760	0.739	0.765	0.764
Miscellaneous painful tumours	0.625	(0.587–0.661)	0.661	0.678	0.689	0.650	0.655

CI = confidence interval, AUROC = area under the receiver operating characteristic curve
