Spectral analysis of blood pressure data revealed a statistically significant decrease (−3.98 mmHg 2 , p = 0.041) in total SBP variability between day zero (d0) (7.08 ± 1.75 mmHg 2 ) and day 14 (d14) (4.2 ± 0.96 mmHg 2 ), with a similar, but not quite significant, trend in VLF SBP (−1.90 mmHg 2 , p = 0.063) across these time-points (d0: 4.36 ± 0.65, d14: 2.46 ± 0.65 mmHg 2 ) ( Supplementary Figure 8 ).
