Kaplan-Meier curves for recurrence-free survival according to TCF12 staining intensity. IHC staining intensity of TCF12 on a colorectal stage II TMA was used to generate Kaplan-Meier curves for recurrence free survival. Intensity scores were divided in negative/weak/moderate versus strong staining intensity. The log-rank test was used to generate the p-value by comparing the survival curves. Number at risk are listed below the plot and censored samples are indicated with a vertical bar.
