Interaction effect (p = 0.01) between randomised fat group and three groups of change in energy% intake from protein (prot%), in relation to change in triglyceride level. The y-axis displays the mean change of triglycerides in each group, and confidence intervals (CI) correspond to CI:s derived from linear regression using the largest group (low-fat, >2 units increased prot% intake) as the reference. β is shown for the group with the largest deviance from the reference. ▦ basic model, ▨ additional adjustment for change in energy intake.
