Multidisciplinary Delphi consensus statement on minimal standards for clinical metadata and end points in microbiome studies.

Guideline / reviewmicrobiomeguideline
Clinical takeawayNo clinical action yet: this is a consensus statement aimed at harmonizing research practices, not a clinical guideline.
What it foundThe HMA consortium provided 15 recommendations to standardize metadata collection, sampling procedures, data generation, and sharing in gut microbiome-based clinical studies.
ContextThis addresses the lack of standardization in microbiome research, which has been a barrier to comparing and integrating findings across studies.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
