Table 3.
The effect of TB on survival of field voles, as overall lesion positive (i.e. individuals that were positive for a cutaneous lesion at some point in their capture history (tb)), and a time-specific individual TB covariate (indtb)
(The base model was φ(st * dens)+prevrf+mo+yr+sx p mo+yr+rf+n +m+edge. The most parsimonious model is highlighted in bold.)
