Mean (± SD) values for serum lipid, lipoprotein cholesterol and apoB levels at the end of the three dietary periods (n = 61), and means (95% Confidence Intervals) for individual differences between diets.¹

1The subjects consumed each diet for 3 weeks each, in random order. 2Levels on industrial trans fatty acids were recalculated to correct for the slightly higher intake of saturated and the slightly lower intake of total trans and cis fatty acids on the industrial trans diet than on the CLA diet. Corrections were made using the equations of Mensink et al. [16]. 3Variables were analyzed with a mixed linear model, with diet as the repeated factor within subjects and period as a fixed effect. P<0.05 was considered to be a significant effect. When significant, Least Significant Differences t-test procedure was used for pair wise comparisons: 4p<0.001. 5p<0.015. 6p<0.05.
