After accounting for animal ID and subherd as random factors, the variables that affected the degree to which an animal loses schistosomes (model 6) were mostly mediated by factors important to disease progression such as immunity and health.

However, the degree to which an animal gains (model 5) worms was predicted by environmental & host factors mediating exposure. Any variable with an NA means that variable was selected out of that model during model selection. Statistically significant variables (p<0.05) are denoted with a *.
