↵¹Cell entries are mean values based on 5 point Likert scale (1 = least preferred, 2 = somewhat unpreferred, 3 = neither unpreferred nor preferred, 4 = somewhat preferred, 5 = most preferred).
↵²The raw means with different superscripts differ significantly at P < 0.05.
↵³Tukey was used for post-hoc comparison.
