    Published in Cochrane Database of Systematic Reviews

    Methodology

    Cochrane systematic review and meta-analysis of 22 randomised and quasi-randomised trials comparing Astragalus (crude herb or extract) with placebo, no treatment or conventional care in chronic kidney disease.

    Key Findings

    Neither of the primary outcomes (time to renal replacement therapy and all-cause mortality) was reported by any included trial; risk of bias was high in six trials and unclear in the remaining 16, and overall study quality was low.

    Conclusions

    Current evidence for Astragalus in chronic kidney disease comes from small, poor-quality trials and is insufficient to support clinical recommendations.

    Limitations

    Low methodological quality, small trials, mostly Chinese-language publications, no patient-important endpoints reported.

    Supplements Studied

    Study quality was low overall. Our nominated primary outcomes of time to requirement for renal replacement therapy or initiation of dialysis and all-cause mortality were not reported in any of the included studies.
