Table 1.

Results of univariate modelling of the factors influencing IFNγ response magnitude. Int = intercept; Δ age = within-individual age term; mean age = between-individual age term; bTB = bovine tuberculosis status (‘−ve’ = negative, ‘+ve’ = positive, ‘ex’ = excretor); cond = condition; d.f. = degrees of freedom; ΔAICc = deviation in AICc from the best-supported model; AW = adjusted model weight for models included in the top model set; ✓ = factors level included in the model with their corresponding contrasts adjacent to them; terms in italic denote the best-supported model. For unabridged model output, see electronic supplementary material, S3.
