Table 2.
Symbols reflect the estimates of the final models (SE in brackets): α = infection density (INF), β = intercept, γ = gender (estimate for female), μ = length and λ = total energy. - = variable not significant in the model, and empty columns = variable was not included in the full model. Units of parameters: 1 = mg O2 kg−1 h−1, 2 = g, 3 = g L−1, 4 = %, 5 = kJ g−1 and 6 = g g liver−1. SMR = standard metabolic rate. Asterisks indicate the significance level of the estimated parameters (*P < 0.05, P < **0.01, ***P < 0.001). R2 indicates how much of the variation of data each model explains. All reported estimated model parameters are on log scale except for organ size where estimates are on a log-10 scale
