Effects of transcutaneous vagus nerve stimulation in individuals aged 55 years or above: potential benefits of daily stimulation

Figure 3. Visit 1 baseline Δ RR (A) and BRS (B) significantly predicted change at visit 2 baseline, where lower baseline Δ RR (A) and BRS (B) in visit 1 were associated with greater increases in baseline Δ RR (A) and BRS (B) in visit 2. In A, Δ Δ RR reflects the difference between maximum and minimum RR intervals (Δ RR) between visit 1 baseline and visit 2 baseline. In B, Δ BRS reflects the difference in BRS between visit 1 baseline and visit 2 baseline.
