The length and width values are the median values (first quartile-third quartile)
Significant level is P < 0.05
*#Different lowercase letters (a, b, c) in the same column indicate significant differences (P < 0.05), and similar lowercase letters indicate no significant difference (P > 0.05) among groups (Bonferroni adjustment)
