Parameters	15-20 (Years) n = 13	21-31 (Years) n = 37	t-value	p-value
GGT	23.98 ± 9.32 U/L	23.02 ± 6.05 U/L	0.4	> 0.05 (NS)
ALT	25.70 ± 7.65 U/L	23.57 ± 10.31 U/L	0.7	> 0.05 (NS)
AST	18.69 ± 7.42 U/L	22.22 ± 6.32 U/L	1.7	> 0.05 (NS)
TP	7.52 ± 1.54 g/dL	7.67 ± 1.23 g/dL	0.4	> 0.05 (NS)
ALB	5.28 ± 0.92 g/dL	5.31 ± 0.76 g/dL	0.11	> 0.05 (NS)
df = 48; p > 0.05

This table indicates that the mean serum GGT, ALT, AST activities, levels of TP and ALB of age group 15-20 years and 21-31 years in control subjects, showed no statistical significant difference (p > 0.05) in the values obtained from the age group 15-20 years when compared with age groups 21-31 years.
