Association between SERPINE1 expression and clinical characteristic. A Association between SERPINE1 expression and patient’s age as analyzed by analysis of variance (21–40 Yrs: n = 12; 41–60 Yrs: n = 90; 61–80 Yrs: n = 149; 81–100 Yrs: n = 32); B Association between SERPINE1 expression and patient’s gender as analyzed by analysis of variance (male: n = 156; female: n = 127); C Association between SERPINE1 expression and patient’s race as analyzed by analysis of variance (Caucasian: n = 193; African-American: n = 55; Asian: n = 11); D Association between SERPINE1 expression and patient’s nodal metastasis status as analyzed by analysis of variance (N0: n = 166; N1: n = 70; N2: n = 47); E Association between SERPINE1 expression and patient’s cancer stage as analyzed by analysis of variance (stage1: n = 45; stage2: n = 110; stage3: n = 80; stage4: n = 39); F Association between SERPINE1 expression and patient’s histological subtype as analyzed by analysis of variance (adenocarcinoma: n = 243; mucinous adenocarcinoma: n = 37) (p < 0.05 indicates a significant difference)
