Table 3. Comparison of the two groups in terms of change in USG (AP-L) (in mm) over time (n = 40).

USG: ultrasonography; IQR: interquartile range; AP-L: anteroposterior - longitudinal view

USG (AP-L)	Group		P-value for comparison of the two groups at each of the time points (Mann-Whitney U Test)

12 Weeks	5.52 (0.97)	5.73 (1.27)	0.655
P-value for change in USG (AP-L) over time within each group (Friedman Test)	<0.001	<0.001
