Abstract

The metabolic syndrome includes both dyslipidemia and impaired vascular function. Because extended-release niacin (ERN) and prescription omega-3 acid ethyl-esters (P-OM3) independently improve these characteristics, we tested their effects in combination. Sixty metabolic syndrome subjects were randomized to 16 weeks of treatment on dual placebo, P-OM3 (4 g/day), ERN (2 g/day), or combination in a double-blind trial. Lipoprotein subfractions and vascular endpoints were measured and tested using ANCOVA. ERN increased HDL cholesterol by 5.4 mg/dl from baseline (P = 0.04), decreased triglycerides (TG) by 39 mg/dl (-21%, P = 0.003), and decreased the augmentation index, which is a measure of vascular stiffness, by 3.5 units (P = 0.04). P-OM3 reduced TG by 26 mg/dl (-13%, P = 0.04). Combination treatment increased HDL cholesterol by 7.8 mg/dl (P = 002) and decreased TG by 72 mg/dl (-34%) but there was no improvement in vascular stiffness. Detailed analysis of lipoprotein subfractions revealed increased large, bouyant HDL(2) (3.3 mg/dl; P = 0.002) and decreased VLDL(1+2) (-32%; P < 0.0001), among subjects treated with combination therapy, that were not present with either therapy alone. ERN and P-OM3 alone improved characteristics of metabolic syndrome; however, whereas subjects on combination therapy did not have improved vascular stiffness, TG and HDL levels improved as did certain lipoprotein subfractions.

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

  • In a Japanese trial of about 600 patients with hypertriglyceridemia, 4 g/d O3AEE reduced triglycerides by about 22%, while 2 g/d O3AEE and 2 g/d IPE each reduced triglycerides by about 11% after 12 weeks.

    “Triglyceride reductions from baseline were ≈22% in the 4 g/d O3AEE group and ≈11% for both the O3AEE and IPE 2 g/d groups after 12 weeks”

    From Omega-3 Fatty Acids for the Management of Hypertriglyceridemia: A Science Advisory From the American Heart Association (2019) · cites this paper as [52]

    The Methods (Study design; page unavailable) describe a 16-week trial with 60 participants assigned to placebo, 4 g/day prescription omega-3, 2 g/day niacin, or their combination—not the claimed 12-week, approximately 600-patient comparison of O3AEE and IPE doses. The Results (Effects on lipid and lipoprotein levels; page unavailable) report a 13% triglyceride reduction with omega-3 alone, rather than approximately 22%. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

  • In that trial, non-HDL-C decreased by 4% to 6% in all three groups at 12 and 52 weeks.

    “Non-HDL-C decreased by 4% to 6% in all 3 groups at 12 and 52 weeks”

    From Omega-3 Fatty Acids for the Management of Hypertriglyceridemia: A Science Advisory From the American Heart Association (2019) · cites this paper as [52]

    The Methods (Study design; page unavailable) describe four groups treated for 16 weeks, not three groups assessed at 12 and 52 weeks. Results (Table 3; page unavailable) report non-HDL-C decreases in all four groups, but as changes in mg/dL (−5.9, −23, −11, and −7.3), not a 4%–6% decrease in three groups at those time points. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

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.
