  1. Hazard rates are expressed relative to the hazard rates of the default level of the fixed factor, which is constrained to be 1. The default level for “Pathogen Type” is Allopatric treatment. Lower CL and Upper CL indicate lower and upper bounds of 95% confidence intervals. Confidence intervals that do not contain 1 signify statistical significance and are shown in bold. Higher hazard rates are equivalent to lower survivorship in the hosts
