Screening of independent prognostic clinical factors. A. The KM curves of age. Left: age in the TCGA prognostic KM curve. Green and red represent the KM curves of the sample group below or above 65 years of age, respectively. Middle and right: KM curves related to prognosis based on the prognosis score prediction model for the sample groups aged under and over 65 years old. Green and red curves represent low- and high-risk samples, respectively. B. The KM curves of metastasis. Left: tumor metastatic factors in TCGA sample prognostic KM curves. Green and red represent the KM curves of the sample group below or above 65 years of age, respectively. Middle and right: KM curves related to prognosis based on the prognosis score prediction model for the sample groups with and without tumor metastasis. Green and red curves represent low- and high-risk samples, respectively
