• During the second reporting period, iCARE4CVD progressed from foundational work to integrated implementation. Efforts focused on strengthening the federated infrastructure, advancing artificial intelligence based modelling and expanding engagement with patients and clinicians.
• The federated architecture is now operational for metadata exploration and secure multi cohort analysis. Fifteen metadata dictionaries covering more than one hundred fifty thousand individuals were mapped and validated, with additional cohorts undergoing harmonisation. The Cohort Explorer gained multi cohort comparison tools, ontology based knowledge graphs and improved query functions. Integration with the data clean room and the blockchain governance prototype also advanced.
• Biomarker research progressed with completion of an artificial intelligence supported pipeline for scalable evidence extraction. The first systematic review on interleukin six was completed, and digital biomarker reviews for heart failure and coronary artery disease were initiated with harmonised search methods.
• Patient participation increased through three national panels, early outputs and a presentation at a scientific congress. The PROMs and PREMs scoping review was submitted, and the INSPIRE eHealth preference survey recruited more than seven hundred individuals, informing motivational modelling and patient centred tool design.
• In Work Package 5, progress was made in risk prediction, precision medicine modelling and explainable artificial intelligence. Harmonised datasets were processed through an extended readiness pipeline. New survival and causal models were developed to estimate individual treatment effects and identify treatment modifiers, and models predicting hospitalisation and mortality were benchmarked across cohorts. Dashboards and explainable artificial intelligence tools are prepared for prospective validation.
• Trial preparation in Work Package 6 advanced with completion of the electronic case report form, the data flow architecture and the decision engine design. Although model delivery delays shifted timelines, all core documents and laboratory infrastructure are in place.
• Work Packages 7 and 8 progressed health economic frameworks, pathway mapping and regulatory readiness. Patient journeys were adopted for pathway design, resource use metrics were defined for cost effectiveness analysis and the regulatory roadmap aligned with federated analytics and emerging standards for artificial intelligence in medicine.
