* Description of methods used to measure low-density lipoprotein (LDL) subfractions, comparison of different methods, variability of measures, link between therapies to alter LDL subfractions and CVD outcomes, and association between LDL subfractions and incident and prevalent CVD.
† No clinical CVD outcome, not LDL subfractions, not an analysis of baseline lipoprotein subfractions, or no original data.
