Note: * = p ≤ 0.05, ** = p ≤ 0.01, *** = p ≤ 0.001. Standard deviations appear in parentheses below means; means in the same row sharing the same superscript letter do not differ significantly from one another at p ≤ 0.05; means that do not share superscripts differ at p ≤ 0.05 based on Scheffé test post-hoc paired comparisons.
