WNK4 and Hypertension: There was no evidence to support any significant association between WNK4 G1156666A polymorphism and hypertension risk (allele genetic model: OR = 1.12, 95% CI: 0.74–1.69, P = 0.60, Figure 2b; dominant model: OR = 1.08, 95% CI: 0.68–1.71, P = 0.74; and homozygous model: OR = 3.40, 95% CI: 0.86–13.54, P = 0.08).
