Systolic blood pressure (BP) measured via tail cuff in male (n = 5) and female (n = 5–6) Dahl salt-sensitive rats expressed as the change (Δ) between baseline and after a 4-wk normal-fat diet (NFD) or high-fat diet (HFD; A), expressed as absolute values weekly in the HFD-fed group and at baseline and after 4 wk in the NFD-fed group (B) and expressed as the percent increase from baseline (C) in both treatment groups. One female rats on the NFD died before final BP measurements. All data are presented as means ± SE. Tail-cuff data within each group were analyzed using repeated-measures ANOVA. Δ and percent increases in systolic BP were compared using two-way ANOVA. +P < 0.05 vs. baseline in the same treatment group in both male and female rats; *P < 0.05 vs. same-sex NFD-fed control group; #P < 0.05 vs. female rats of same treatment group (NFD or HFD).
