Primary Outcome Mean Arterial Pressure
Mean arterial pressure increased significantly more
between baseline and the last week of study participation
in the quiet rest group than in the guided imagery group
(Table 2). When the influences of baseline mean arterial
pressure and gestation were controlled using multiple
linear regression, the contribution of study group to
mean arterial pressure change was no longer statistically
significant (b = )0.19, p = 0.14). Overall, 25 women
(86.2%) in the quiet rest group had a mean arterial pressure
increase, versus 17 (54.8%) in the guided imagery
group, and 2 women in the guided imagery group and 11
in the quiet rest group had no change in mean arterial
pressure; however, 12 (38.7%) from the guided imagery
group had a mean arterial pressure reduction compared
with 3 (10.3%) in the quiet rest group (Fisher’s exact
test = 7.24, p = 0.02)
