Abstract

A higher intake of dietary fiber may decrease the risk of developing cardiovascular disease. We examined the association between dietary fiber and serum concentration of C-reactive protein (CRP), a possible predictor of cardiovascular events, using data from the National Health and Nutrition Examination Survey 1999-2000. Among 3920 participants > or = 20 y old, dietary fiber intake was inversely associated with serum CRP concentration. The odds ratio (OR) for increased CRP concentration (>3.0 mg/L) was 0.49 (95% CI 0.37-0.65; P for trend < 0.001) for the highest quintile of fiber intake compared with the lowest. Adjustment for age, gender, race, education, smoking, physical activity, BMI, total energy, and fat intake resulted in a slight attenuation (OR 0.59; CI 0.41-0.85; P for trend = 0.006). Excluding participants with cardiovascular conditions, diabetes, or cancer did not alter the results. Our findings indicate that fiber intake is independently associated with serum CRP concentration and support the recommendation of a diet with a high fiber content.

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

  • Adiponectin levels are 13% lower in the highest quintile of dietary GI than in the lowest.

    “Adiponectin levels were 13 % lower in the highest quintile of dietary GI than in the lowest quintile.”
  • In 780 diabetic men from the Health Professionals' Follow-Up Study, dietary GI and GL are both significantly inversely associated with plasma adiponectin concentration in a dose-dependent fashion after adjustment.

    “After adjustment for other factors, dietary GI and GL were both significantly inversely associated with plasma adiponectin concentration in a dose-dependent fashion.”
  • In diabetic males (n 780, Health Professionals' Follow-Up Study), cereal fibre is positively associated with adiponectin levels after controlling for confounders.

    “In a study with diabetic males (n 780, Health Professionals' Follow-Up Study), cereal fibre was positively associated with adiponectin levels after controlling for a number of confounding factors (315) .”
  • For dietary GL, adiponectin levels are 18% lower in the highest quintile than in the lowest.

    “For dietary GL, adiponectin levels were 18 % lower in the highest quintile than in the lowest.”

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.
