Values are in mean and standard deviation. BMI = body mass index, SFA = dietary saturated fatty acid, PUFA = dietary poly-unsaturated fatty acid, Chol = dietary cholesterol, KeysF = Keys dietary lipid factor, TC = serum total cholesterol concentration, TG = triglycerides concentration, HDLc = high-density lipoprotein cholesterol concentration, LDLc = low-density lipoprotein cholesterol concentration. P diff = P for difference by analysis of variance.
