We measured efflux from macrophages to apolipoprotein B-depleted serum from 263 specimens and found instances in which serum having similar high-density lipoprotein cholesterol (HDL-C) differed in their efflux capacity. Thus, we wanted to elucidate why efflux capacity could be independent of total HDL-C or apolipoprotein A-I (apoA-I).
