EMM (SE) estimated marginal means (standard error). Only those with significant differences (p ≤ 0.001, presented in bold typeface) were listed in the post-hoc test column and Bonferroni’s test was used as a post-hoc procedure
The significance for the post-hoc test was set as p < 0.05. *p < 0.05, **p < 0.01, ***p < 0.001
