Our model to estimate CETP-mediated TG redistribution using only the ratios TG/(TG + CE) and surfaces of TRL, IDL, LDL, and HDL (22) is applicable in postprandial lipemia as well—with or without discrimination of TRL into CM and VLDL + CMR fraction (d > 1.006). The gene discussed is CETP; the disease is hyperlipidemia.
