  • SHEPHERD's model can be publicly released without the risk of exposing patient information.

    “A notable byproduct of training the model on synthetic data is that SHEPHERD’s model can be publicly released without the risk of exposing patient information52.”

    From Few shot learning for phenotype-driven diagnosis of patients with rare genetic diseases (2025) · cites this paper as [52]

    The Fidelity tests section says synthetic datasets could be freely shared and would substantially lessen patient-privacy concerns. It does not establish that SHEPHERD’s model can be released without risk; the same section warns that publicly available model weights can leak patient information. (LLM, conf=0.84)

  • Synthetic data generators were applied for building similar replicas of original private datasets while maintaining consistent statistical properties.

    “Additionally, the synthetic data generators were applied for building similar replicas of the original private datasets, while maintaining consistent statistical properties [161,162].”

    From Challenges in AI-driven Biomedical Multimodal Data Fusion and Analysis (2025) · cites this paper as [162]

    The Fidelity tests section says synthetic datasets that accurately capture the original data distribution could be shared instead of patient data, supporting the idea of statistically similar substitutes for private datasets. But it presents this as a possibility, not an established outcome of applying generators, and cautions that current generative models are not ready for off-the-shelf use. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Deep generative models are used to create synthetic images such as skin lesions, pathology slides, colon mucosa, and chest x-rays, thereby greatly improving the reproducibility of medical data.

    “For instance, deep generative models are used to create synthetic images such as skin lesions, pathology slides, colon mucosa, and chest x-rays, thereby greatly improving the reproducibility of medical data [71].”

    From Generative AI in medical practice: in-depth exploration of privacy and security challenges (2024) · cites this paper as [71]

    The Fidelity tests section lists synthetic images of skin lesions, pathology slides, colon mucosa and chest X-rays. It says synthetic data could contribute to improving reproducibility, but does not show that generating these images has greatly improved it; the section also cautions that current generative models are not ready for off-the-shelf use. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Pretraining with synthetic fine-grained morphological descriptions has utility, suggesting the scaling potential of TITAN pretraining with synthetic data.

    “Additionally, we demonstrate the utility of pretraining with synthetic fine-grained morphological descriptions, suggesting the scaling potential of TITAN pretraining with synthetic data89–91.”

    From A multimodal whole-slide foundation model for pathology (2025) · cites this paper as [89]

  • Research has used synthetic data in AI for medicine and health care to address the scarcity of annotated medical data in the real world.

    “By contrast, research has used synthetic data in AI for medicine and health care to address the scarcity of annotated medical data in the real world [71].”

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.
