Comparison of the mean BMI of patients at various visits within the groups using paired t-test

BMI	Baseline visit Mean±SD	1st visit Mean±SD	t (P) df=16 a*b	2nd visit Mean±SD	t (P) df=16 a*c	3rd visit Mean±SD	t (P) df=16 a*d
Cases	23.34±2.43	23.46±2.54	–1.661 (0.116)	23.26±2.51	0.572 (0.575)	23.11±2.48	1.236 (0.234)
Controls	20.75±4.1	21.07±4.02	–3.816 (0.001**)	21.40±4.02	–6.719 (0.001**)	21.78±3.98	–9.638 (0.001**)

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