Figure 1. The effect of genotype and dietary sodium on plasma Nt-proANP levels during saline challenge is shown after 1 week of a (A) low-salt diet or (B) high-salt diet (P = 0.018 for genotype effect, P < 0.001 for diet and saline effects).

Figure 1

Samples for measurement of plasma Nt-proANP levels were obtained at baseline and hourly for 8 hours after the start of saline infusion. AA, rs5068 major homozygote; AG, rs5068 heterozygote.
