Cutoff optimization of Ki-67 by correlation with DFS in the DFSP data. a The hazard ratio (HR) including 95% CI is plotted depending on the cutoff. A vertical line designates the dichotomization showing the most significant correlation with DFS. The distribution of Ki-67 in the 56 tumors is shown as a rug plot at the bottom of the figures. b Kaplan–Meier analysis of DFS for Ki-67 < 17% and Ki-67 ≥ 17%
