Decreasing mean intensity of average HER2 membranous staining in the consecutive tissue multi-control sections. Mean intensity of the average HER2 membranous stain and Mean percentage of cells with complete membranous staining are represented by the orange and blue interpolation lines and orange dots/blue circles, respectively. The values are calculated from all 4 samples of the tissue multi-control. Mean intensity of the membranous stain decreases (increasing pixel values) in the consecutive sections (r=0.32, p<0.0001).
