  1. Note: Estimated marginal means (EMM) and standard errors (SE) are reported as predicted by the regression model. Significant differences (Sig. diff.) between a given category and other categories within the same categorial predictor are denoted with the respective comparison category identifiers in brackets (p < .05, Bonferroni-adjusted for multiple comparisons)
