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].
