Values are means ± standard error of the means; n, number of animals; Δ, difference between Dahl S and congenic values; SBP, systolic blood pressure in mmHg; DBP, diastolic blood pressure in mmHg; MAP, mean arterial pressure in mmHg; PP, pulse pressure; P in females, one-way ANOVA followed by Holm-Sidak’s test for multiple comparisons; P in males, t-test.
