  1. Only models with Δ i  ≤ 2 and the global model (in italic) are shown here with the number of parameters (K), the quasi-likelihood adjusted deviance (QDEV), the quasi-likelihood adjusted AIC for small sample size (QAICc), the difference between the QAICc of the top model and a given model i (Δ i ) and the Akaike weights (w i ). Variables considered are the condition index (c, which can indicate HCC or SMI values), sex (s) and time (t). Constant parameters are noted (.). Interactions are indicated by (*) and additive effects by (+)
