Coexpression of Matrix Metalloproteinase-7 and Tissue Inhibitor of Metalloproteinase-1 as a Prognostic Biomarker in Gastric Cancer

Figure 3

The association between expression of MMP-7 and TIMP-1 and postoperative survival in gastric carcinoma. (a) Comparison in terms of expression of MMP-7. (b) Comparison in terms of expression of TIMP-1. (c) Comparison between the three groups. (d) Comparison between the two groups. −: negative expression; +: positive expression; both −: patients whose tumour tissue expressed neither MMP-7 nor TIMP-1; −/+: patients whose tumour tissue expressed only TIMP-1; +/−: patients whose tumour tissue expressed only MMP-7; and both +: patients whose tumour tissue expressed both MMP-7 and TIMP-1.
