*n=25 for body weight, plasma cholesterol at week 6, and plasma triglycerides at week 6 owing to missing data;
†n=23 for body weight owing to missing data;
‡the p values refer to difference between diet and control groups for the change from baseline to week 12. Differences between groups were analysed by Student’s t test for independent samples.
Significant change from baseline: §p<0.001;
¶p<0.01. Within-group differences at weeks 3, 6, and 12 compared with baseline were evaluated by Student’s t test for paired samples.
