At baseline, Kaplan-Meier curves showing patient survival probability stratified by BSI categories. All the 146 patients included in the study were studied at the time of prostate cancer diagnosis with bone scans. In accordance with their BSI values at baseline, these patients were stratified in three BSI categories: BSI =0 (n =84), BSI ≤1 (n =30) and BSI >1 (n =32). These three groups demonstrated significantly different 5-year survival rates of 80%, 60% and 25%, respectively (p<0.0001).
