Correlation between weak, medium and strong RHDV binding and A, B and H type 2 expression or no expression.

For each strain, animals were split into 3 equal groups according to the intensity of binding (weak, medium or strong) and association with A, B and H type 2 expression or lack of expression was tested by chi-square analysis. NS = not significant. *p<0.05. **p<0.005. ***p<0.0005. †correlation with low binding (inverse correlation).
