Meta-Analysis of the Association Between Whole Grain Intake and Coronary Heart Disease Risk

Tang, Gang, Wang, Duan, Long, Jun, Yang, Fan, Si, Liangyi·2015·The American Journal of Cardiology

Abstract

Epidemiologic studies evaluating the association of whole-grain intake with risk for coronary heart disease (CHD) have produced inconsistent results. The aim of this meta-analysis was to summarize the evidence from observed studies regarding the association between whole-grain intake and risk for CHD. Pertinent studies were identified by searching the Web of Knowledge and PubMed up to July 2014. A random-effects model was used to combine the results. Publication bias was estimated using Begg's funnel plot and Egger's regression asymmetry test. Ultimately, fourteen reports of 18 studies (15 cohort studies and 3 case-control studies) involving 14,427 patients with CHD and 400,492 participants were used in this meta-analysis. Pooled results suggested that highest whole-grain intake amount compared with the lowest amount was significantly associated with reduced risk for CHD (summary relative risk 0.787, 95% confidence interval 0.743 to 0.833), with no between-study heterogeneity observed (I(2) = 0%, p = 0.537). The association was significant in cohort studies but not in case-control studies. Inverse associations were also found in the United States and Europe. No publication bias was found. In conclusion, this meta-analysis indicates that higher whole-grain intake has a protective effect against CHD.

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.
