Figure 4From: Prognostic relevance of Bmi-1 expression and autoantibodies in esophageal squamous cell carcinoma Kaplan-Meier curves with univariate analyses (log-rank) for patients with low Bmi-1 expression versus high Bmi-1 expression tumors. The cumulative 5-y survival rate was 41.3% in the low Bmi-1 protein expression group (n = 81) (bold line), but it was only 33.2% in the high expression group (n = 91) (dotted line) (P < 0.05, Log-rank).Back to article page
