The cross tabulation of the patients' HER2 score range and maximum values represents variation of the analysis results between individual patient's spots. VE1max and VE2max - first and second visual evaluation by the pathologist, DAmax - digital analysis score. Accordingly, VE1range, VE2range, and DArange represent range between a minimum and maximum spot HER2 score value.
