Given the fact that the composition of the gut microbiota is different in men and women, this study aimed to describe in detail the placebo response of the gut microbiota in healthy and FMF women.\nMaterials and Methods: The bacterial response to placebo was fully evaluated on a previous PhyloChip™ DNA microarray-based assay (GEO Series; accession number GSE111835).\nResults: The change in the total number of operational taxonomic units in healthy women exposed to placebo is more than that of healthy men, in contrast to FMF people (704 vs. 140 and 409 vs. 7560, respectively [p < 0.05]). Gut Firmicutes diversities are more sensitive to placebo, whereas Akkermansia muciniphila remained unchanged after the placebo administration for both healthy and FMF people. Gut Prevotellaceae and Enterobacteriaceae diversities of healthy subjects and FMF women are also almost unchanged from placebo. Meanwhile, only 56.35% of gut Enterobacteriaceae diversities in FMF men were placebo resistant.\nConclusion: The response to a placebo varies depending on a person's gender and health status. Healthy and FMF women's placebo study groups could be avoided by excluding placebo-sensitive 704 of 18,725 and 409 of 18,725 bacterial diversities, respectively. Because the placebo causes changes in all gut bacterial phyla in healthy and FMF women, and only the representatives of Enterobacteriaceae and Prevotellaceae families and A. muciniphila spp. are not affected by placebo, these bacteria can be considered as possible markers in women-related nutritional/clinical trials. Data on the response of the gut microbiota in healthy women to placebo might be used in studies of diseases other than FMF. The response of gut bacteria from different taxonomic affiliations to placebo may provide a basis for uncovering the role of these bacteria in the gut-brain axis.", "claims": [{"id": "claim-method", "statement": "For statistical analysis, the Excel Multibase 2015 add-in (NumericalDynamics, Tokyo, Japan) was applied, as well as the Mann–Whitney U test and paired t-test (Excel 2016).", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:39439767", "locator": "sections[2] \"Material and Methods\" paragraph 6", "quote": "For statistical analysis, the Excel Multibase 2015 add-in (NumericalDynamics, Tokyo, Japan) was applied, as well as the Mann–Whitney U test and paired t-test (Excel 2016)."}], "state": "complete"}, {"id": "claim-data-access", "statement": "Research data are available from the author.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:39439767", "locator": "sections[12] \"Data Availability Statement\" paragraph 2", "quote": "Research data are available from the author."}], "state": "complete"}, {"id": "claim-target-result", "statement": "The change in the total number of operational taxonomic units in healthy women exposed to placebo is more than that of healthy men, in contrast to FMF people (704 vs. 140 and 409 vs. 7560, respectively [p < 0.05]).", "kind": "quantitative", "target": {"value": 0.05, "unit": "p-value", "tolerance": null, "source": "The change in the total number of operational taxonomic units in healthy women exposed to placebo is more than that of healthy men, in contrast to FMF people (704 vs. 140 and 409 vs. 7560, respectively [p < 0.05])."}, "evidence": [{"asset": "source:pmid:39439767", "locator": "sections[0] \"Abstract\" paragraph 3", "quote": "The change in the total number of operational taxonomic units in healthy women exposed to placebo is more than that of healthy men, in contrast to FMF people (704 vs. 140 and 409 vs. 7560, respectively [p < 0.05])."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "complete", "objective": "The change in the total number of operational taxonomic units in healthy women exposed to placebo is more than that of healthy men, in contrast to FMF people (704 vs. 140 and 409 vs. 7560, respectively [p < 0.05]).", "steps": [{"id": "read_published_estimate", "order": 1, "name": "Read the published estimate from the source", "kind": "other", "state": "complete", "blocked_on": null, "description": "The claim, method and evidence span published with the source article.", "duration_hours": null, "parameters": {}, "inputs": ["source:pmid:39439767"], "outputs": ["the published estimate and its evidence"], "instruments": [], "reagents": []}, {"id": "obtain_source_data", "order": 2, "name": "Obtain the source data from the named repository", "kind": "data-preparation", "state": "complete", "blocked_on": null, "description": "The GEO series accession resolves and its sample accessions are listed.
