Fig 3. Effects of high-salt/normal potassium and high-salt/low potassium on mean blood pressure and heart rate in C57BL/6N mice.

Mice were monitored with telemetry in the dark (A, B, C) and light (C) periods of a modified light/dark cycle. NS = normal salt diet (n = 17), LS = low salt diet (n = 15), HS = high Na⁺/normal K⁺ diet (n = 8) and HS/LK = high Na⁺/low K⁺ diet (n = 6). One-way ANOVA per light phase followed by Tukey’s post-hoc test; *: p<0.05 compared to NS diet; #: p<0.05 HS/LK compared to HS.
