BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure. † n = 56; n = 55 for total fat mass; n = 54 for visceral fat mass. 1 A repeated-measures ANOVA with two factors (treatment, post-pre phase) was performed to compare changes over time (post-pre) between groups. Mean ± SD pre-intervention (at the beginning of the 12-week trial) and post-intervention (at the end of the 12-week trial). 2 p-value to compare changes over time from the baseline to 12 weeks (pre vs. post) within each group (placebo or brown seaweed extract). 3 p-value to compare change over time (pre vs. post) between groups (placebo vs. brown seaweed extract).
