View larger version (16K): [in a new window]   Fig. 1. Systolic blood pressure during stress, and change in systolic blood pressure from pre-stress to during stress (mean ± S.E.). Systolic pressure was significantly lower during mental stress on flax seed (p = 0.003 for within-subject main effects; p-value for treatment-time interaction was 0.46). For the change in systolic pressure during stress p = 0.33 for treatment effect, p = 0.80 for treatment-time interaction.
