Table 6.

Comparison of the mean BMI of patients at various visits between the groups using student t-test

	Cases		Control		t (df=32)	P
	Mean	SD	Mean	SD
BMI at baseline in kg/m2	23.35	2.44	20.75	4.16	2.21	0.034*
BMI at 1st visit in kg/m2	23.46	2.55	21.07	4.03	2.071	0.047*
BMI at 2nd visit in kg/m2	23.26	2.52	21.40	4.03	1.619	0.115
BMI at 3rd visit in kg/m2	23.12	2.49	21.79	3.98	1.167	0.252

P<0.05 is statistically significant, and P<0.001 is statistically highly significant
