Figure 5. Plot of the first two principal components (PC1 and PC2) from analysis of the four lesion descriptive variables; lesion type (purulent, caseous, or calcified), scale (single or multiple), size (<10 mm, 10–50 mm, >50 mm in diameter at widest axis) and pathology score (=pathscore) (small lesion at 1 focus, small lesion at more than one focus, extensive necrosis).

The points are jitter to reveal overlapping points and coloured by abattoir with 80% ellipses for each.
