RESULTS
Participants
The trial was conducted in Adelaide, South Australia, between
August 2011 and March 2012. Patients with uncontrolled
hypertension on medical record were recruited from two
metropolitan general practices. Of the 840 patients invited, 14%
responded and were screened for eligibility, and 84 patients were
enroled randomly allocated to one of four treatment groups. Five
patients withdrew before further assessment because of personal
reasons unrelated to the trial (Figure 1). Baseline characteristics of
the 79 patients participating in the trial were not significantly
different between the garlic and placebo groups (Table 1). A total
of 42 men and 37 women with a mean age of 70±12 years
participated in the trial. Participants took on average 2±1
different types of antihypertensive medication (range 0–4), with
angiotensin II receptor blockers the most often prescribed (46%).
Family history of cardiovascular disease was reported by almost
half of the participants, including premature cardiovascular events
by 15% (Table 1).
Compliance and withdrawals
Despite doctors being aware of a patient’s participation in this
trial, BP medication regimen was changed for four participants
during the trial (g1: nผ2 and g2: nผ1 before 4 weeks; Pผ1
before 12 weeks). As change in BP medication was expected to
have influenced patient’s BP and biased the effect of the trial
supplement, the correlating data points were excluded from
planned adjusted analysis.
Patient’s compliance was assessed by calendar entries. We
excluded data points from planned adjusted analysis if compliance
was o80%, which was more pronounced around the
Christmas/New Year’s holiday period.
Five patients withdrew after 4 weeks, three due to gastrointestinal
complaints (g4: nผ2; Pผ1), one due to a broken arm
(g4: nผ1) and one was no longer interested in participating
(g1: nผ1).
Blood pressure
Intention-to-treat analysis of 79 patients revealed a significant
reduction in SBP from baseline in the garlic-2 group compared
with placebo over 12 weeks (mean diff. SBP±s.e. (95% confidence
