Abstract

Background: Low-density lipoprotein cholesterol (LDL-C) has been the cornerstone measurement for assessing cardiovascular risk for nearly 20 years. Content: Recent data demonstrate that apolipoprotein B (apo B) is a better measure of circulating LDL particle number (LDL-P) concentration and is a more reliable indicator of risk than LDL-C, and there is growing support for the idea that addition of apo B measurement to the routine lipid panel for assessing and monitoring patients at risk for cardiovascular disease (CVD) would enhance patient management. In this report, we review the studies of apo B and LDL-P reported to date, discuss potential advantages of their measurement over that of LDL-C, and present information related to standardization. Conclusions: In line with recently adopted Canadian guidelines, the addition of apo B represents a logical next step to National Cholesterol Education Program Adult Treatment Panel III (NCEP ATPIII) and other guidelines in the US. Considering that it has taken years to educate physicians and patients regarding the use of LDL-C, changing perceptions and practices will not be easy. Thus, it appears prudent to consider using apo B along with LDL-C to assess LDL-related risk for an interim period until the superiority of apo B is generally recognized.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Even at peak postprandial concentrations, the number of chylomicron-apoB48 particles in healthy individuals is usually < 1% and the number of VLDL-apoB100 particles is < 10% of the number of LDL-apoB100 particles.

    “ApoB can be measured in the nonfasting state because even at peak postprandial concentrations, the number of chylomicron-apoB48 particles in healthy individuals is usually < 1% and the number of VLDL-apoB100 particles is < 10% of the number of LDL-apoB100 particles [12].”

    From Quantifying atherogenic lipoproteins for lipid-lowering strategies: Consensus-based recommendations from EAS and EFLM (2020) · cites this paper as [12]

    The MEASUREMENT ISSUES section (p. 9) says fasting is not required for apo B measurement, and the apo B-CONTAINING LIPOPROTEINS AND CVD RISK section (p. 2) says most plasma apo B is associated with LDL. Neither passage gives the claimed <1% chylomicron-apoB48 or <10% VLDL-apoB100 particle ratios at peak postprandial concentrations in healthy individuals. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • ApoB is the structural protein for all non-HDL lipoproteins and exists as 2 isoforms: apoB100, the major isoform in VLDL, IDL, LDL, and Lp(a), and apoB48 in chylomicrons and chylomicron remnants.

    “It is the structural protein for all non-HDL lipoproteins and exists as 2 isoforms: apoB100, the major isoform in VLDL, IDL, LDL, and Lp(a), and apoB48 in chylomicrons and chylomicron remnants [12].”

    From Quantifying atherogenic lipoproteins for lipid-lowering strategies: Consensus-based recommendations from EAS and EFLM (2020) · cites this paper as [12]

    The ‘apo B STRUCTURE AND FUNCTION’ section (p. 2) identifies two isoforms and calls apo B-48 the structural protein of chylomicrons. The ‘apo B-CONTAINING LIPOPROTEINS AND CVD RISK’ section (p. 2) lists VLDL, IDL, LDL, and Lp(a) as apo B-containing particles. Our copy does not explicitly assign apo B-100 to each of those particles or mention apo B-48 in chylomicron remnants. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • apoB can be measured more accurately, more precisely, and more selectively than LDL-C or non-HDL-C.

    “Taken together with the evidence that apoB can be measured more accurately, more precisely, and more selectively than LDL-C or non-HDL-C,1,29–31”

    From Discordance among apoB, non-high-density lipoprotein cholesterol, and triglycerides: implications for cardiovascular prevention (2024) · cites this paper as [30]

    The MEASUREMENT ISSUES section (pp. 9–10) says apoB measurement is more amenable to standardization than LDL-C measurement, reports between-laboratory precision for apoB assays, and identifies specificity problems with direct LDL-C assays. It does not establish that apoB is more accurate, precise, and selective than non-HDL-C, or directly compare precision with LDL-C. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Measurement of apolipoprotein B (apoB) or advanced measurement of LDLP can be used to assess the number of LDL particles.

    “Measurement of apolipoprotein B (apoB), the major protein component of LDL, or advanced measurement of LDLP (not yet widely available) can also be used to assess the number of LDL particles [10,12].”
  • ApoB can be measured in the nonfasting state.

    “ApoB can be measured in the nonfasting state because even at peak postprandial concentrations, the number of chylomicron-apoB48 particles in healthy individuals is usually < 1% and the number of VLDL-apoB100 particles is < 10% of the number of LDL-apoB100 particles [12].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
