Results from a binomial regression on the presence of corpora lutea in female badgers between March and December for different age classes (age), seasons and body conditions (quality–a value derived by dividing bodyweight by body length).

Asterisks denote significance where* = P** = P*** = PAge and Season were treated as categorical variables in the model, whereas quality was treated as a continuous variable. Body condition values were normalised (z.Condition) prior to analysis. Asterisks indicate significance level.
