Table 3.

Observed and expected frequencies among the NAFLD patients and control subjects using Hardy–Weinberg equilibrium.

Groups	Genotypes		Allele A	Allele G	Observed frequency	Expected frequency	P-value
NAFLD patients	AA	120	240	0	120	121.08	0.2560
	AG	25	25	25	25	22.84
	GG	0	0	0	0	1.08
	Total	145	265	25	145	145.00
Controls	AA	105	210	0	105	107.76	0.0540
	AG	40	40	40	40	34.48
	GG	0	0	0	0	2.76
	Total	145	250	40	145	145.00

As shown above, the frequencies of either the genotypes or alleles in both groups were in Hardy–Weinberg equilibrium.
