Furthermore, the serum levels of AOPPs were significantly negatively correlated with the FC content of the total LDL (LDL-FC/LDL-apoB) in the HVs and patients with MS, as well as with the FC content of LDL subclasses 3–6 in the HVs and LDL subclasses 5 (LDL5-FC/LDL5-apoB) and 6 (LDL6-FC/LDL6-apoB) in the patients with MS. Here, APOB is linked to myeloid sarcoma.
