SPHN Connector - a scalable pipeline for generating validated knowledge graphs from federated and semantically enriched health data.
Article in BMC medical informatics and decision making, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe integration and reuse of heterogeneous health data, including clinical records, cohort studies, and omics datasets, are essential for advancing modern biomedical research. Knowledge graphs offer a powerful means to semantically link such data, enabling interoperability and reuse. The Swiss Personalized Health Network has developed a comprehensive semantic interoperability framework to implement the FAIR (Findable, Accessible, Interoperable, Reusable) principles at a national level.
methodsThis paper presents the strategy adopted and resulting SPHN Connector tool for enabling data providers to transform their local data into semantically enriched knowledge graphs following the RDF and related Semantic Web standards. Rather than requiring centralized data transformation, the SPHN Connector allows each institution to build knowledge graphs locally from their heterogeneous data sources, maintaining data governance at the source while ensuring semantic interoperability across sites.
resultsThe SPHN Connector tackles the technical challenges in federated knowledge graph construction. It converts diverse data formats into SPHN-compliant semantically enriched RDF, and offers capabilities for data transformation, de-identification, and validation, particularly for iterative deliveries.
conclusionThese generated datasets can then either be integrated centrally or used in a federated way, allowing for the linkage of information from the same patient, for example, clinical routine data and omics metadata, as well as the combination of data from different patients across sites.
