F values are given for fixed effects while log likelihood ratios (LLR) are given for random effects. Statistically significant values (P<0.05) are shown in bold and marginally significant values (P<0.1) are shown in italic. The Akaike Information Criterion (AIC) value of the model used is given for each variable. See text for definition of terms.
