Comprehensive analysis of the relationship between cuproptosis-related genes and esophageal cancer prognosis

Figure 2 The Kaplan-Meier survival of patients with esophageal cancer who were classified according to pyruvate dehydrogenase A1 expression. A and B: In esophageal cancer, patients with low pyruvate dehydrogenase A1 (PDHA1) expression levels had better overall survival (A) and progression-free survival (B) than patients with high PDHA1 expression levels. The significance of the difference between high and low expression was calculated using the log-rank test.
