  1. Results are expressed as mean + SEM (minimum – maximum). a,b,c Values within the same line that do not share a common superscript letter are significantly different from each other (p < 0.05). TC = total cholesterol; TG = triglycerides; LDL = low-density lipoprotein; HDL = high-density lipoprotein; AI = atherogenic index.
