Identification of prognostic risk genes. a Correlation analysis among the 8 best prognostic genes in GSE53625. b KM survival analysis displayed high the expression of KIF11correlated with poor prognosis in ESCC patients. c The correlation of KIF11 mRNA expression with tumor cell purity (left) and the degree of CD8⁺ T cell infiltration (right) in ESCC was analyzed with TIMER 2.0. d mIHC stained by a ESCC tissue microarray. Representative pictures (left) of mIHC assay and the summarized results (right) are shown (n: 70 patients). The data are presented as the means ± standard deviations (SD). Statistical analysis is performed with Pearson correlation analysis (a), Log-rank test (b), Wilcoxon test (c) and Student's t-test (d). *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
