Fig. 3From: CD31 and VEGF are prognostic biomarkers in early-stage, but not in late-stage, laryngeal squamous cell carcinomaReduced expression of VEGF correlates with improved survival in early stage LSCC. Patients with negative N-stage (n = 67) (a) and low T-stage (T1 + T2, n = 50) (b) were grouped into either VEGF high or VEGF low and further examined in terms of their survival. Kaplan Meier analysis of survival and log rank test were performedBack to article page
