From: Down-regulation of TM4SF is associated with the metastatic potential of gastric carcinoma TM4SF members in gastric carcinoma

A: Staining intensity B: Precentage of positive Tumor cells C: score
0 = no staining 0 = 0% positive cells  
1 = weak staining 1 =< 10% positive cells  
2 = moderate staining 2 = 10 - 50% positive cells A × B = C
3 = strong staining 3 = 51 - 80% positive cells  
  4 => 80% positive cells
