Multivariate analysis of prognostic factors for overall survival (n = 96)

Variable	HR, 95 % CI	p value
Other distant metastases	3.53 (1.13–11.08)	0.030
(No vs. Yes)

Legend: The clinical factors that were statistically significant (p < 0.10) in a univariate analysis were analyzed further in a multivariate analysis with a stepwise selection of variables. P values <0.05 were regarded as statistically significant in multivariate analysis. Only other sites of distant metastases were selected by a stepwise selection of factors in the final models
