¹Data are expressed as (). Values in the same column with different superscripts are significantly different (). ^uvSignificant () difference between protein levels within the same lipid level. ^xySignificant () difference between lipid levels within the same protein level. TG = triglyceride; TC = total cholesterol; HDL-C = high-density lipoprotein cholesterol; LDL-C = low-density lipoprotein cholesterol; HDL-C/LDL-C = HDL-C to LDL-C ratio; HDL-C/TC = HDL-C to TC ratio.
