Table 2 ECM1 expression in breast cancer specimens, normal epithelium and lymph nodes

From: Expression and clinical significance of extracellular matrix protein 1 and vascular endothelial growth factor-C in lymphatic metastasis of human breast cancer

   ECM1 mRNA expression   Positive Staining grades of ECM1  
Tissue type N   F rate (%) - + ++ +++ χ 2
Cancer tissues 41 1.25 ± 0.33A   75.6D 10 22 7 2  
Normal tissues 41 0.46 ± 0.10B   9.8E 37 3 1 0  
Lymph nodes 41 0.38 ± 0.18C 4.86** 31.7F 28 9 3 1 39.08**
  1. ** P < 0.01, P < 0.05 is considered statistically significant
  2. "+", "++" and "+++" for ECM1 immunochemistry staining was all grouped together as "+"
  3. A vs. B and A vs. C: P < 0.05, respectively; B vs. C: P > 0.05
  4. χ 2 division:α = 0.05/4 = 0.0125; D vs. E and D vs. F: P < 0.001, respectively; E vs. F: P > 0.0125
