Direction of target modifications

Proportion of target changes in the same category that represent an increase in the target value, % (no.)*
41 (33)
n = 80
SAP to SAP increase, mm Hg, median (IQR)
+10 (10 to 10)
MAP to MAP increase, mm Hg, median (IQR)
+5 (5 to 5)
Proportion of target changes in the same category that represent a decrement in the target value, % (no.)*
59 (47)
n = 80
SAP to SAP decrease, mm Hg, median (IQR)
–10 (–15 to –7.5)
MAP to MAP decrease, mm Hg, median (IQR) –5 (–5 to –5)

Note: CI = confidence interval, IQR = interquartile range, MAP = mean arterial pressure, SAP = systolic arterial pressure.
*Denominator is no. of patients who had new targets of the same blood pressure variable.
