X-tile analysis of the survival data in patients with pancreatic ductal adenocarcinoma. (A, B) The optimal cutoff level of the tumor budding (TB) score is 0.62, which was determined by X-tile and used to define the TB score-low and TB score-high groups. (C) The Kaplan–Meier curve and log-rank test suggest that patients in the TB score-low group survived significantly longer than did those in the TB score-high group. (D) TB scores in the TB score-low and TB score-high groups. The chart includes a box plot, density plot, and a dot plot. The 25th and 75th percentiles are shown as connecting lines between the groups.
