Figure 1.

Plots of incidence rate for the new onset of hypertension. Participants were divided into 2 groups using the salt (sodium) intake targets recommended by the Japanese Ministry of Health, Labor, and Welfare (men <9.0 g/day; women <7.5 g/day [<3.5 and <3.0 g/day, respectively]). The red line indicates participants who were above the recommended dietary salt intake target, and the blue line indicates participants who were below the target at baseline (P<0.001, log-rank; P<0.0001, Gehan-Wilcoxon).
