APOB and myeloid sarcoma: In contrast to the negative correlations between the serum levels of AOPPs and the cholesterol (LDL-C/LDL-apoB), free cholesterol (LDL-FC/LDL-apoB), and phospholipid (LDL-PL/LDL-apoB) contents of total LDL described above, we observed a significant positive correlation between AOPPs and the triglyceride content of large buoyant LDL subclass 1 (LDL1-TG/LDL1-apoB) in both HVs and patients with MS, but a significant positive correlation between AOPPs and the triglyceride content of small dense LDL subclass 5 (LDL5-TG/LDL5-apoB) was only observed in patients with MS.
