^aAdjusted means using RM ANCOVA with pre-post, age, gender, BMI and duration between scope.
^bBonferroni adjustment for 95% CI for difference.
^§No significant difference over time (pre & post consumption) [F (df) = 0.30 (1, 71), p = 0.585], however there was significant interaction between time (pre & post consumption) and group [F (df) = 4.25 (1, 71), p = 0.043].
^¥No significant difference over time (pre & post consumption) [F (df) = 0.01 (1, 71), p = 0.906], however there was significant interaction between time (pre & post consumption) and group [F (df) = 5.56 (1, 71), p = 0.021].
^¤No significant difference over time [F (df) = 0.04 (1, 71), p = 0.840] and no significant interaction between time and group [F (df) = 2.10 (1, 71), p = 0.151].
^†No significant difference over time [F (df) = 1.38 (1, 71), p = 0.243] and no significant interaction between time and group [F (df) = 0.31 (1, 71), p = 0.578].
^₤No significant difference over time [F (df) = 0.27 (1, 71), p = 0.606] and no significant interaction between time and group [F (df) = 1.25 (1, 71), p = 0.267].
