Fig 7. Agreement between the different methods of estrogen receptor-assessment, depicted with Bland-Altman diagrams.

Fig 7

From left to right: 1) Mean value of detected estrogen receptor expression by manual scoring and analysis of slide-scanner images, plotted against difference in detected positivity. 2) Mean value of detected estrogen receptor expression by image-analysis of point-of-care microscope images and of slide-scanner images, plotted against difference in detected positivity. The highest concordance was detected between the two device-based scorings. 3) Mean value of detected estrogen receptor expression by image-analysis of point-of-care microscope images and manual scoring, plotted against difference in detected positivity.
