Table 2.

Statistical results for logistic regression of number of individual Evasterias and Pisaster disease progression (number symptomatic) and mortality (number dead) over time. (Species, time and the interaction of species by time were included as fixed effects, and experimental tank nested in time was included as a random effect. Italics indicate p-values of less than 0.05.)
