Abstract

Exposed surfaces of mammals are colonized with 100 trillion indigenous bacteria, fungi, and viruses, creating a diverse ecosystem known as the microbiome. The gastrointestinal tract harbors the greatest numbers of these microorganisms, which regulate human nutrition, metabolism, and immune system function. Moreover, the intestinal microbiota contains pro- and anti-inflammatory products that modulate immune responses and may play a role in maintaining gut barrier function. Therefore, the community composition of the microbiota has profound effects on the immune status of the host and impacts the development and/or progression of inflammatory diseases. Accordingly, numerous studies have shown differences in the microbiota of patients with and without a given inflammatory condition. There is now strong evidence that the gut microbiome regulates bone homeostasis in health and disease, and that prebiotic and probiotics protect against bone loss. Herein, the evidence supporting the role of the microbiota and the effects of prebiotic and probiotics will be reviewed.

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

  • Gut microbiome health affects nutrient production, host growth, and immune homeostasis.

    “GM health also affects nutrient production, host growth, and immune homeostasis [25,26,27].”

    From Osteoporosis: Molecular Pathology, Diagnostics, and Therapeutics (2023) · cites this paper as [27]

    The paper’s opening discussion says gut microorganisms regulate human nutrition and immune-system function. The section “Microbiota Regulates Bone Growth and Bone Mass Acquisition” also describes microbiota-dependent changes in body growth in mice. The copy discusses nutrient absorption and use, but does not establish the claimed effect on nutrient production. (LLM, conf=0.85)

  • Complex diseases such as diabetes mellitus, transient ischemic attacks, and rheumatoid arthritis have been linked to changes in the gut microbiome.

    “Moreover, complex diseases, such as diabetes mellitus (DM), transient ischemic attacks, and rheumatoid arthritis, have all been linked to changes in the GM [25,26,27].”

    From Osteoporosis: Molecular Pathology, Diagnostics, and Therapeutics (2023) · cites this paper as [27]

    The main text (page unavailable) links changes in the gut microbiome to diabetes risk. It discusses rheumatoid arthritis in connection with the oral microbiome, not the gut microbiome, and does not link transient ischemic attacks to microbiome changes. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Bone-active cytokines are released directly by immune cells in the gut, absorbed, and then circulate to the bone, playing a pivotal role in the gut microbiome-immune-bone axis.

    “Bone-active cytokines are released directly by immune cells in the gut, absorbed, and then circulate to the bone; these cytokines play a pivotal role in the GM–immune–bone axis [15,27].”

    From Osteoporosis: Molecular Pathology, Diagnostics, and Therapeutics (2023) · cites this paper as [27]

    In “Microbiota and the Bone Loss Induced by Sex Steroid Deficiency,” the paper considers gut-produced cytokines circulating to bone but says it is still unclear whether that occurs. It instead describes preliminary evidence favoring immune cells that travel from the gut to bone marrow and produce cytokines there. The claim presents the proposed direct route as established. (LLM, conf=0.88)

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.
