In contrast, the BP slope in the IH patients showed a trend towards a decrease with each hour (−0.3 mmHg/hr) during the first 24 hours, and this change was different from not only the same time period in controls (p=0.002, Figure 1 ), but also when compared to hours 25–44 in the IH patients (p=0.001).
