The increase in fibrous cap thickness correlated with the decrease in serum levels of low-density lipoprotein cholesterol ( R = -@ ; p < @ ) , malondialdehyde-modified low-density lipoprotein ( R = -@ ; p = @ ) , high-sensitivity C-reactive protein ( R = -@ ; p = @ ) , and matrix metalloproteinase-@ ( R = -@ ; p < @ ) , and the decrease in grade of OCT-derived macrophages ( R = -@ ; p = @ ) .
