Table 2
Genotype distribution in control subjects and in essential hypertension patients

Variable	Control subjects	Essential hypertension	P value
Number of subjects	14	66
Genotype*			0.36
G/G	13 (92.9)	50 (75.8)
G/C	1 (7.1)	15 (22.7)
C/C	0 (0)	1 (1.5)

Values are presented as number (%). *Genotype distribution not agreed with Hardy-Weinberg equilibrium is confirmed by Pearson’s χ² analysis (χ²=54.53, P=0.000).
