Figure 1: X-tile analysis of survival data from the SEER database. X-tile plot of the training set is displayed in the (a). The optimal cutoff value marked by the black circle in the Figure 1a is shown by a histogram of the entire cohort (b), and a Kaplan–Meier plot (c). P values were calculated using the cutoff point defined in the training set and validating it to the validation set. The figure shows the optimal cutoff points for young patients with gastric cancer (3.9 and 7.0 cm, P < 0.001)
