Younger Age Is Associated with Poorer Survival in Patients with Signet-Ring Cell Carcinoma of the Colon without Distant Metastasis

Figure 2

X-tile plot of age at diagnosis in the SEER cohort of patients with SRCC of the colon. -axis represents all age cutoff values from low to high (left to right) to define the high and low subset. Brighter pixels indicate stronger association between age at diagnosis and cancer-specific survival (CSS). The plot shows the brightest pixel (marked by the black circle) when the study cohort is divided into the high and low subset using 35 years of age as the cutoff. Green color indicates continuous direct association between increasing age at diagnosis and greater CSS.
