Kaplan-Meier plots for metastasis-free survival (MFS) stratified by tumor type. The survival probability is plotted against the time to event (primary tumor diagnosis to bone metastasis diagnosis in months) for each primary tumor type. The survivor function is shown with its 95% confidence interval (95% CI). The number at risk at the beginning of the respective x-axis time intervals are shown below the graph. The illustrations in the graphs are right truncated for a number at risk ≤5
