Notes: Values are expressed as the mean (standard deviation); Δ, variation after 90-day intervention;
a
significant difference between before and after intervention; comparison before and after intervention (Wilcoxon’s test); variable comparison between groups (Mann–Whitney U-test).
Abbreviations: LDL, low-density lipoprotein; HDL, high-density lipoprotein; TC, total cholesterol; TG, triglycerides; VLDL, very low-density lipoprotein; LG, linseed oil + nutritional guidelines group; PG, placebo + nutritional guidelines group; TEV, total energy value.
