Relationship between circulating levels of linoleic acid and cholesterol fractions in the entire population. (A) Correlation between levels of linoleic acid (LA) and total cholesterol, LDL- and LDL-cholesterol in the entire population. The dotted lines show the regression lines: (i) total cholesterol: R2=0.595, P<0.0001, total cholesterol=0.79×LA+1.52; (ii) LDL-cholesterol: R2=0.455, P<0.0001, LDL-cholesterol=0.567×LA+0.583; and (iii) HDL: R2=0.076, P=0.001, HDL-cholesterol=0.120×LA+0.726. (B) Circulating levels of LA adjusted for age, gender and lipoproteins variables assessed by ANCOVA. Values are means±SD.
