APOB and cardiovascular disorder: In recent years, numerous diagnostic indicator models for cardiovascular diseases have been proposed, such as the monocyte-to-high-density lipoprotein cholesterol ratio (MHR), lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), platelet-to- lymphocyte ratio (PLR), apolipoprotein B to apolipoprotein A-1 ratio (apoB/apoA-1), and the low-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (LDL-c/HDL-c) (16, 17).
