Table 3 EN2 protein expression in human ovarian tissue (Cohorts 1 and 2)

From: Engrailed-2 (EN2) – a novel biomarker in epithelial ovarian cancer

  1. The product of the EN2 staining intensity score (0–3+) and the percentage of positively stained cells score (0–4) was calculated. The resultant score of 0–4 represented EN2 negative staining, and 5–12 represented EN2 positive staining. Comparative analysis of the tumour sections demonstrated a significant difference between the EOC and borderline tumours, compared with the benign and normal tissues (x2 = 26.854, p < 0.001)
