CRP = C-reactive protein; BP = blood pressure; HR = heart rate; IQR = interquartile range.
1
Values (excepting rows for CRP median [IQR]) are mean (SEM).
*
Self-selected diet group higher than intervention group, P<0.05, t-test.
**
Change within group compared with baseline, P<0.05, paired t-test.
†
The standard self-selected diet group was higher at 3 months than the combined intervention groups, although not significantly, P=0.06 Wilcoxon two-sided rank sum test.
