Subjects with morbid obesity (MO) group. ^∗Statistically significant at p ≤ 0.05. Duncan's method was used to find the significant difference between two groups as follows: The same small letters indicate that there was no significant difference between the two groups, while the difference letters indicate that there was a significant difference between this two groups.
