OP = overweight placebo, OT = overweight treatment, NP = normal weight placebo and NT = normal weight treatment.
Values at the start of the study (Time 0) listed in the first column are means of data from individuals. Mean changes after 4 weeks and 8 weeks are listed in the second and third columns as ± Standard Deviation. A negative value indicated a decrease in value and a positive number represents an increase in value. %Δ values are percent mean change in value between time 0 and either 4 or 8 weeks. Values* are significant P-value comparisons (< 0.05) between initial values at Time 0 and either 4 weeks or 8 weeks.
