  Figure 2. Truncated violin plots demonstrating the Mayer wave activity in the HR and SBP signals by group and visit. Each violin plot presents the group median (‐ ‐ ‐ ‐) and interquartile range (·····). The truncation of each plot represents the minimum and maximum observation for each group. The dark circles within each plot represent each participant's data. * P < 0.001.

  Figure 3. Truncated violin plots demonstrating the Mayer wave proportion by group and visit. Each violin plot presents the group median (‐ ‐ ‐ ‐) and interquartile range (·····). The truncation of each plot represents the minimum and maximum observation for each group. The dark circles within each plot represent each participant's data. * P < 0.001.

  Figure 4. Truncated violin plots demonstrating the Mayer wave proportion by RTP group and visit. Each violin plot presents the group median (‐ ‐ ‐ ‐) and interquartile range (·····). The truncation of each plot represents the minimum and maximum observation for each group. The dark circles within each plot represent each participant's data. * P = 0.001, † P = 0.07, ‡ P < 0.0001.

  Figure 5. Truncated violin plots demonstrating the BRSn‐Avg by RTP group and visit. Each violin plot presents the group median (‐ ‐ ‐ ‐) and interquartile range (·····). The truncation of each plot represents the minimum and maximum observation for each group. The dark circles within each plot represent each participant's data. * P < 0.001; † P < 0.05.
