Notes: Values are expressed as the mean (standard deviation); Δ, variation after 90-day intervention; comparison before and after intervention (Wilcoxon’s test). Variable comparison between groups (Mann–Whitney U-test). Values are in bold are statistically significant.
Abbreviations: BMI, body mass index; LDL, low-density lipoprotein; HDL, high-density lipoprotein; TC, total cholesterol; TG, triglycerides; VLDL, very low-density lipoprotein; WC, waist circumference; LG, linseed oil + nutritional guidelines group; PG, placebo + nutritional guidelines group.
