TABLE 4 displays pairwise differences in BP. In all participants, non hypertensive participants, and hypertensive participants, the established and established plus DASH interventions
significantly reduced systolic and diastolic BP in comparison with the advice only group. Although BP change in the established plus DASH group was consistently greater than corresponding BP change in the established group, none of the pairwise differences was statistically significant. The pattern of results was similar in the “on treatment” analyses, which included those individuals in the established and established plus DASH groups (70% and 78% of participants, respectively) who attended more than 15 intervention sessions. For contrasts with the advice only group, BP reductions in the on treatment analyses were approximately 20% to 40% greater than corresponding reductions in the intention to treat analyses.
