Abstract

Objectives The rationale for the current study was to evaluate the efficacy of flaxseed supplementation on important adhesion molecules and inflammatory cytokines in adults.Methods We conducted searches of published literature in PubMed, Scopus, Web of Science, and Google Scholar databases from inception until May 2019. All randomized controlled trials (RCTs) which investigated the effects of flaxseed supplementation on the circulating concentrations of C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), vascular cell adhesion protein 1 (VCAM-1), E-selectin, and intercellular adhesion molecule 1 (ICAM-1) were included in our analysis. Results were summarized using weighted mean differences (WMDs) by random-effects model.Results Forty eligible RCTs, including 2520 participants were identified. The results of the meta-analysis revealed flaxseed supplementation reduced the concentrations of CRP (WMD = -0.387 mg/L; 95% CI: -0.653, -0.121, p = 0.004), IL-6 (WMD = -0.154 pg/Ml; 95% CI: -0.299, -0.010, p = 0.036), and VCAM-1 (WMD = -22.809 ng/ml; 95% CI: -41.498, -4.120, p = 0.017) but had no significant effect on TNF-α (WMD = -0.077 pg/mL; 95% CI: -0.317, 0.163, p = 0.530), ICAM-1 (WMD = -8.610 ng/ml; 95% CI: -21.936, 4.716, p = 0.205), and E-selectin (WMD = -1.427 ng/ml; 95% CI: -4.074, 1.22, p = 0.291).Conclusions These findings showed that flaxseed supplementation may improve some circulating concentrations of specific adhesion molecules and inflammatory cytokines. However, well-designed trials are needed to confirm the range of non-significant and/or equivocal findings.

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.
