(a) Meta-analysis of the overall association between the C79G polymorphism and hypertension comparing C vs. G. n indicates the total number of C alleles; N indicates the total number of C alleles plus G alleles. (b) Meta-analysis for the association between the C79G polymorphism and systolic blood pressure (SBP)⩾160 mm Hg and/or diastolic blood pressure (DBP)⩾95 mm Hg hypertension comparing CC vs. CG+GG. n indicates the total number of the CC genotype; N indicates the total number of the CC genotype plus the CG+GG genotype. (c) Meta-analysis for the association between the C79G polymorphism and SBP⩾160 mm Hg and/or DBP⩾95 mm Hg hypertension comparing C vs. G. n indicates the total number of C alleles; N indicates the total number of C alleles plus G alleles.
