超低低密度膽固醇

The conclusion that elevated serum cholesterol level causes coronary artery disease is based on studies of families with hyperlipidemia for which Brown and Goldstein won their Nobel prize.  All the statements on LDL-C and stroke are based on epidemiological studies which are difficult to conclude cause-and-effect relationship.  I would take most of these so called meta analysis or study with a grain of salt.
