Our study showed a higher OR 2.62 (95% CI, 1.24–5.76; P = 0.006) compared to a recent meta-analysis [15] in Han Chinese population which reports high association between AGT M235T polymorphism and hypertension (OR = 1.54; 95% CI, 1.16–2.03; P = 0.002). The gene discussed is AGT; the disease is Hypertension.
