Implementing informed consent in federated medical research: a blueprint designed to safeguard data subject rights in Germany.
Article in Journal of translational medicine, 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 establishment of the complementary infrastructures Medical Informatics Initiative (MII) and the Network of University Medicine (NUM) has significantly advanced the medical research landscape in Germany. Both infrastructures focus on the cross-institutional integration of health data as the basis for strengthening medical research, with the MII focusing on the standardization and integration of routine university clinical data and the NUM representing a central infrastructure for clinical studies and data sharing. Within the project 'NUM Routine Data Platform' (NUM-RDP), a federated record linkage approach was implemented across 34 affiliated German university hospitals. Accordingly, a federated Trusted Third Party (fTTP) performed pseudonymization and privacy-preserving record linkage across all the participating sites. This work aims to extend the established fTTP approach to managing consent and withdrawal while considering the current legal frameworks and research initiatives for the use of health data.
methodsA concept for an extended fTTP, termed 'fTTP Consent', is proposed to bridge communication gaps between different sites, facilities and components. This allows for central coordination for the implementation of patients' consent decisions regarding the storage, transfer and scientific use of their health data in a uniform manner.
resultsTwo practical use cases for an 'fTTP Consent' have been identified and conceptualized. First, the cross-site improvement of workflows and automated processes should be performed to ensure that consent data are correct in formal, legal, semantic and syntactic terms. Second, the cross-site improvement of automated notification processes for new or updated consent data, including respective withdrawal- and objection-processes, should be performed.
conclusionsIn this study, the 'fTTP Consent' has been proposed to reduce communicatory and personnel efforts. The correct and up-to-date realization of data subject rights should be ensured using the NUM-RDP as an example. The designed concept could help to overcome challenges in different consent scenarios (opt-in, opt-out). Furthermore, it could streamline communication and data linkage processes between institutions and countries in future research projects.
