Scatter plots of (A) ERα, (B) ERβ, (C) PR, and (D) AR mRNA levels in gastric tumors and corresponding adjacent normal mucosa (n = 60). The line indicates the median value. The mRNA levels were normalized to β-actin and statistical differences were determined using Wilcoxon matched-pairs signed-rank test.
