Figure 1 Distribution of the results of the "Quick" score evaluation conducted on the three infiltrating ductal carcinomas (IDC), X, Y, Z, used at assessment. The bold line represents the median score, the bottom and top of the boxes, the 1st and 3rd quartiles, respectively, and the range bars, the lowest and highest scores, respectively. The slightly different numbers for the three tumours reflect loss of tissue from the microscope slides; n, number of participating laboratories.
