Similarly, the DTI-ALPS index was significantly lower in the group with Two Abnormal BP patterns compared to the Normal group [ p = 0.004, r rb = 0.95 IC 95% [0.81, 0.99]] and showed a trend when the One Abnormal group was compared to the Normal one [ p = 0.073, r rb = 0.71 IC 95% [0.15, 0.93]], see Figure 3 .

Associations between the continuous sleep BP percentage of change and DTI-ALPS The correlational analyses in the full sample revealed low positive associations between DTI-ALPS and the percentage of SBP change between awake and sleep, which did not reach statistical significance ( r = 0.36, p = 0.11).
