Coronary Heart Disease and Iron Status: Meta-Analyses of Prospective Studies

Danesh, John, Appleby, Paul·1999·Circulation

Abstract

BACKGROUND: Studies of iron status and coronary heart disease (CHD) have yielded conflicting results. In a systematic review ("meta-analysis"), we quantitatively assessed epidemiological associations reported in prospective studies. METHODS AND RESULTS: Studies were identified by computer-assisted searches of the published literature, scanning of relevant reference lists, hand searching of relevant journals, and discussions with relevant authors. The following was abstracted: size and type of cohort, mean age, mean duration of follow-up, assay methods, degree of adjustment for confounders, and relationship of CHD risk to the baseline assay results. Twelve studies were identified, involving a total of 7800 CHD cases, with several reporting on >1 marker of iron status. For serum ferritin, with 570 CHD cases in 5 studies, comparison of individuals with baseline values >/=200 versus <200 microg/L yielded a combined risk ratio of 1.0 (95% CI, 0.8 to 1.3). For transferrin saturation, with 6194 CHD cases in 5 studies, comparison of individuals in the top third with those in the bottom third of the baseline measurements yielded a combined risk ratio of 0.9 (95% CI, 0.7 to 1.1). Comparisons of individuals in top and bottom thirds of baseline measurements also yielded nonsignificant risk ratios in combined analyses of studies involving total iron-binding capacity (combined risk ratio, 1.0; 95% CI, 0.7 to 1.5), serum iron (0.8; 95% CI, 0.7 to 1.0), and total dietary iron (0.8; 95% CI, 0.7 to 1.1). CONCLUSIONS: Published prospective studies do not provide good evidence to support the existence of strong epidemiological associations between iron status and CHD.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Randomised controlled trials show that supplementation with different quantities of soya protein did not affect CRP, IL-6, IL-18, sICAM-1, sVCAM-1 or sE-selectin.

    “Several randomised controlled intervention trials have shown that supplementation with different quantities of soya protein did not affect markers of inflammation (CRP, IL-6, IL-18, sICAM-1, sVCAM-1 and sE-selectin) (Table 7) (345,347 -364) .”

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.
