Significant effects between linear mixed models model comparisons are marked in bold. Note, that due to multiple comparison correction alpha-level was set to 0.05/3 = 0.0167. P values represent the ANOVA model comparison of linear mixed models with fixed and random effects.

Mean ± SD. Significant models of interest compared to the null model in bold (LMM comparison p < 0.001).
